CROSS REFERENCE TO RELATED APPLICATIONS 
     This is a national stage application of PCT/CN2008/001570, filed on Sep. 3, 2008, which claims priority of PCT/CN2007/002649, filed on Sep. 4, 2007. The disclosures of these prior filed applications are incorporated herein by reference in their entirety. 
     FIELD OF THE INVENTION 
     This invention relates to a type of cloth and leather material, especially materials having accessories and separate conductively sensitive areas that can change its condition when external force is applied 
     BACKGROUND 
     As we know, there are many technologies incorporating conductive material into cloth or leather material for making electrical circuits or to electronic components. Included here are some technologies that incorporate conductive material into cloth material for making electric switches. For example, a bendable switch is disclosed in U.S. Pat. No. 7,145,432, which makes use of a triple-layered textile material arranged in sequence to make an electric switch. Furthermore, U.S. Pat. No. 6,642,467 (corresponding to China Patent No. CN1252762C) discloses an electric switch that utilizes an upper layer and a lower layer of a conductive material sandwiching an elastic material. Included in it is a button component, which comprises a metallic ring and a piece of rope/thread that passes through the ring. The switch is operated by pulling on the rope/thread. It has 4 objects in all, and the rope is a non-conductive component. If it is to be in the form of a pressure sensor or a tension sensor, it needs to add a pressure-sensitive component, which is made of a Piezoelectric material, in order to produce an analog signal. Such a switch is easily damaged. The layered textile materials in the afore-mentioned electric switches are common and numerous. However, the manufacturing process using these materials is somewhat complicated. 
     Furthermore, U.S. Pat. No. 6,596,955 discloses devices having conductive materials fixed onto a zipper. The use of these is limited to cloths that have zippers. In addition, it can&#39;t be repaired by the user. In addition, China Patent No. CN1666308 discloses an electric switch made of an upper part and a lower part. However, because it is difficult to incorporate this into a cloth material, the manufacturing process is somewhat complicated. 
     In addition, some materials are used as signal or electric current transmitting devices, as disclosed in U.S. Pat. No. 7,154,071. Again, as in the above-described products, these devices have the disadvantages of requiring complicated manufacturing processes. U.S. Pat. Nos. 4,237,886 and 6,970,731, disclose snap-on button devices that can easily detach with prolonged use. U.S. Pat. No. 6,210,771 discloses a 2-part structure that can be used as a switch matrix. However, this switch not only easily gives a false signal, but its function is also easily affected by a wet cloth material caused by sweat or rain. Besides, this device can only measure pressure, but can&#39;t measure strain. For example, as disclosed in U.S. Pat. No. 7,210,939 (corresponding to China Patent CN1791337A), a button-hole interconnect is used as a conductor. This device includes an opening and a button interconnect; these two have to be operated manually by the user to be able to connect to the power source or an electronic equipment. Once electrically connected, it cannot be disconnected. Therefore, in terms of the environment and energy-saving, it is not ideal because it cannot automatically change its state of being conductive or non-conductive based on changes in outside forces. In addition, it can&#39;t distinguish the extent of conductivity once it is connected. 
     SUMMARY OF INVENTION 
     In view of the above-mentioned disadvantages, one of the objectives of this invention is to provide a type of cloth material with separate conductive areas that can be incorporated into a user&#39;s clothes or leather jacket. Therefore, the user can carry it around conveniently and it does not interfere with the user&#39;s motion. 
     Another objective of this invention is to provide a type of cloth material with separate conductive areas that can automatically cut off its power in the event that the textile layer gets wet. 
     Another objective of this invention is to provide a type of cloth material with separate conductive areas that can be used as a strain gauge or a pressure gauge for a user to measure strain or pressure. 
     Another objective of this invention is to provide a type of cloth material with separate conductive areas that can be used as a position change sensor gauge, a speedometer gauge, or accelerator gauge. 
     In addition, another objective of this invention is to provide a type of cloth material with separate conductive areas that can be used as an electrode. 
     Another objective of this invention is to provide a type of cloth material with separate conductive areas that can allow a user to easily replace defective parts when the system malfunctions. 
     Another objective of this invention is to provide a type of cloth material with separate conductive areas that can produce digital signals, because the resistance value is either very small or infinitely large, and the noise can be processed by a Schmitt trigger. 
     In order to achieve these objectives, this invention provides a type of cloth materials with separate conductive areas. A cloth material of the invention may include at least one first layer and at least one extension part; the first layer has a conductive sensor area and a non-conductive area located on the periphery of the first conductive area; the extension part is equipped with an accessory and a connecting part that connects with the accessory; a part of the accessory forms a second conductive area, the position of which corresponds to the first layer first conductive area. The first conductive area and the second conductive area are inductively connected (coupled). The inductive coupling conditions can change with an external force. Based on this, when an external force is applied, the first conductive area may come into contact with the second conductive area to form an electrically-conductive path. When the external force disappears, the system will revert to its original condition. Cloth materials of the invention may be incorporated into user&#39;s clothes or leather jackets. Therefore, a user can carry it around conveniently and it does not interfere with the user&#39;s motion. 
     Based on the above technical aspects, cloth materials with separate conductive areas in accordance with the invention have at least the following advantages and beneficial effects:
         1) This invention&#39;s cloth materials with separate conductive areas may be used as an accessory to clothing apparel. If broken, such an accessory can be removed. When not in use, the accessory can be removed as a whole unit. The extent of use is only limited, hence, it is simple and easy to use;   2) The digital signal is either 0 or 1, hence energy efficient;   3) This invention&#39;s cloth materials with separate conductive areas may use conventional clothing materials that look like ordinary clothing and not extravagant. It is washable and not easily destroyed;   4) Basically, one component may have several functions, e.g., as a switch, electrode, pressure sensor, or signal transducer.

     DETAILED DESCRIPTION 
     In order to further explain this invention&#39;s technological methods used and its effects, the following preferred examples with accompanying drawings are presented. The following description is provided to answer the questions regarding this invention&#39;s cloth materials with separate sensor areas with regards to their application methods, structure, special qualities and effectiveness. 
     Please refer to  FIGS. 1 and 2 : this invention&#39;s first preferred example that provides a type of cloth material  10  with separate sensor areas includes one first layer  12 , several extension parts  16 , one electrical control circuit  192 , and one output device  194 . 
     On top of the first layer  12  includes several first sensor areas  13 , one non-sensor area  14 , and two reference areas  15 . The first sensor areas  13  and the reference area  15  are both conductive. The first sensor areas  13  is arranged in a matrix and penetrates the first layer  12 . The non-sensor area  14  is located between and around the first sensor areas  13 , and can be made of a non-conductive, non-magnetic textile fiber material or leather. The reference area  15  is far away from the first sensor areas  13 . The first sensor areas  13  and the reference area  15  can be formed in the following manner (but not limited to it):
         1. By means of a single textile process, weaving non-conductive fibers and conductive fibers together, either by knitting, weaving, tatting, embroidering, or other appropriate means;   2. By means of embedding, sticking or weaving a conductive metallic plate into the first layer  12 ;   3. By means of sewing fine, conductive wires into the first layer  12 ;   4. By means of applying a conductive material with an adhesive substance over the first layer  12 .   5. By means of sticking or sewing a conductive cloth material over the first layer  12 .       

     The above-mentioned non-conductive textile fibers may include, but not limited to, cotton, hemp or nylon, while the conductive fibers may include polymer conductive fibers or conductive metallic fibers, or weaving a stainless steel fiber and a non-conductive fiber together, or applying a conductive substance over a non-conductive fiber. The percentage of the conductive fibers in the first sensor areas  13  can account for from 1% to 100%. 
     The extension parts  16  each contain an accessory  17  and a connecting part  18 . This accessory  17  may be spherical in shape, pillar-shaped, polygon-shaped or saucer-shaped, is elastic, and can change shape due to pressure and revert to its original shape if the external force disappears. It can be made of rubber, foam, sponge, spring, cotton, spandex, lycra, SBR (Styrene Butadiene Rubber), or foam-based material. On the surface of any of the accessories  17 , there may be three circular second sensor areas  172 . Each circle represents a resistance value. These second sensor areas  172  are made of a conductive material and may be formed in a similar fashion as the afore-mentioned first sensor areas  13 , such as: 1, sewing together non-conducting fibers and conducting fibers into an accessory component  17  using a textile process, for example knitting, weaving, or other appropriate process; 2, Embedding, sticking, or sewing conductive metal plates into the accessory  17 ; 3, Sewing conductive fine wires into the accessory  17 ; 4, Applying or sticking conductive materials on the accessory  17 ; 5, Sticking, sewing or gluing an already conductive cloth material onto the accessory  17 . The location of the second sensor area  172  corresponds to the location of the first sensor area  13  in the first layer  12 . The connecting part  18  in this example is made of 3 interconnected conductive fine wires and another thick wire woven together. One end of the connecting part  18  is connected with the accessory  17 , and the other end is connected with the non-sensor area  14  of the first layer  12 . The accessory itself may contain high-density material, like metal or glass, which will cause it to hang downward. The connecting art  18  of the extension part  16  is electrically connected to the corresponding second sensor areas  172 . The extension part  16  is separated from the reference area  15  of the first layer  12 . In addition, the accessory  17  may be a button, shiny disc, or a pearl similar to accessories used on modern garments. The accessory  17  may also contain high-density material, like metal or glass, which will cause it to hang downward. 
     The control circuit  192  may be removably fixed on the first layer  12 . It may be a printed circuit board or an IC board with an integrated power source. The control circuit  192  is electrically connected to the first sensor areas  13  and the reference area  15  on the first layer  12 . It is also electrically connected to second sensor areas  172  of the accessory  17  via the connecting art  18 . Based on the above, when a user applies pressure on the accessory  17  pushing it towards the first layer  12 , the second sensor areas  172  of the accessory  17  may come into contact with the corresponding first sensor areas  13 , thereby forming a circuit among the first sensor areas  13 , second sensor areas  172 , and the control circuit  192 . 
     The output device  194  is electrically connected to the control circuit  192 , and is a device that can send signals wirelessly. When a user applies pressure on the accessories in different locations, the control circuit  192  will command the output device  194  to send different signals based on the different locations of the accessories where pressure has been applied. The output device  194  and control circuit  192  may also be fixed on the accessory. 
     Furthermore, the control circuit  192  may include a resistance-multiplexed switches which can be used to measure the resistance in the circuit. When the user applies an increasing amount of pressure, the accessory  17  may change shape accordingly, causing more and more of its second conductive areas  172  to contact the first sensor areas  13 . At this time the resistance in the circuit will become smaller. Such a system can function as a pressure gauge. The control circuit  192  may be programmed with a resistance threshold value. When it detects a resistance lower than the threshold, the control circuit  192  will command the output device  194  to send a signal. Otherwise, if the resistance is higher than the threshold, the control circuit  192  will not issue a command, thereby preventing accidentally triggering the system. 
     Furthermore, the second sensor areas  172  may be designed to have three insulated conductive wires that are independently connected to the control circuit  192 . Therefore, when the three second sensor areas  172  on the accessory  17  come into contact with the first sensor area  13 , the first sensor area  13  and the second sensor areas  172  can produce three different signals to the control circuit  192 . In addition, depending on the amount of pressure exerted by the user, the number of conductive loops (circuits) formed on the cloth material  10  will vary. Hence, the cloth material with separate sensor areas  10  may be used as three-stage switches. Each stage of the switches can represent different amounts of external force applied. This can show three sets of digital signals rather than analog signals, thereby doing away with complicated signal processing, and also avoiding the need for an AD converter. At the same time, this can detect force directionality: the accessory  17  is pressed against the cloth material  10  to have a response. If the cloth material  10  is pressed towards the accessory  17 , there will be no response. Because behind the cloth material  10  is a user&#39;s body, this will greatly decrease the possibility of false signals. 
     The two reference areas  15  on the first layer  12  is spaced apart, and they are also separated from the first sensor areas  13  on the first layer  12  and from the extension part  16 . Therefore, when the cloth material  10  is used normally, the two reference areas  15  would not form a loop (circuit), neither will any of the two reference areas  15  come into contact and form a loop with the first or second sensor areas  13 ,  172 . Nevertheless, if the two reference areas  15  form a loop, or either of the two reference areas  15  forms a loop with either the first sensor areas  13  or the second sensor areas  172 , the control circuit  192  will immediately cut off power to prevent short-circuit, causing electrical skock to the user. At the same time, the control circuit can also command the output device  194  to send an alarm signal to notify the user. Similarly, when the first sensor areas  13  on the first layer  12  form a loop among themselves, or the second sensor areas  172  of the extension part  16  form a loop among themselves, or if the cloth material  10  changes its condition when external force is applied, gets wet or loses its function, the control circuit  192  may cut off the power, and at the same time may act as a wetness indicator gauge. 
     Based on the above-mentioned structure, the cloth material  10  with separate sensor areas can be made into a piece of clothing for the user to wear, or into a remote control device. The user can press on the accessories  17  at different locations, or on the same accessory to contact different sensor areas  13 , to activate the output device  194  to send different signals wirelessly to switch channels on a TV set, control the sound volume, or set the thermostat control of an air-conditioner. Aside from these, the first layer  12  and the accessory  17  both may have diagrams  126 ,  174  (see  FIGS. 1 and 2 ) to illustrate these functions. Because a cloth material  10  with separate sensor areas may be designed to be incorporated into a cloth or leather worn by a user, it would be convenient for the user to carry around without affecting the user&#39;s motions. 
     In addition, the first layer  12  can be made into a piece of underwear, placing the extension part  16  on the outer side of the first layer  12 . By means of pressing on the accessories  17  at different locations, it will cause the first sensor areas  13  at different locations or reference areas  15  to come in contact with the site to be tested on the user&#39;s skin. Based on this, the first sensor areas  13  can be used as an electrode for EKG, respiration, EMG, EEG, “Transcutaneous Electrical Nerve Stimulation” (TENS) device, or defibrillator. Also, the cloth material  10  with separate conductive areas can be used to provide electric current for an electric clothing to the user warm. In another word, the cloth material  10  with separate conductive areas can be used to transmit not only physiological signals from the user, but also electric current or signals from outside to the user, making it a device for transmitting signals and electric current. This device may be activated only when external force is applied to the first conductive areas and the second conductive areas  172 , such as when a clothe is worn by a user, and may automatically turn off when no external force is applied, such as when a clothe is removed by the user. Therefore, there is no need for the user to constantly turning on and off a switch. Such a device may also transmit multiple signals and electric currents. 
     Furthermore, the cloth material  10  with separate conductive areas may be placed around arm pit, enabling a user to establish electrical conduction simply by pressing his upper arm against the side of his chest. Furthermore, the output device  194  can be an LED, an electric horn or a slim monitor panel, which can emit light, sound or show the pressed location based on electric conductance. 
     In addition, when the cloth material  10  with separate conductive areas is made into an upper body clothing and worn by the user, by analyzing electric conductance between the first and second conductive areas  13 ,  172  at different locations of the user&#39;s body, one can ascertain the actions of the user. For example, by knowing that the first and second conductive areas  13 ,  172  on the anterior chest of the user are not in contact and that the first and second conductive areas  13 ,  172  on the back of the user are in contact with one another, we can ascertain that the user is bending down. Or, when the second conductive areas are in electrical contact with the non-corresponding first conductive areas, one can assume that the user is turning (twisting) his body. When the user turns to the right, the accessory may rotate to the left, coming into contact with a conductive area on the left side. Based on this, the cloth material  10  with separate conductive areas can be used as a testing device for detecting changes in the user&#39;s position, such as to detect falling down. 
     Due to the fact that the magnitude of electrical resistance in a loop is affected by the amount of pressure exerted on the accessory  17 , the cloth material  10  with separate conductive areas can be used as a resistance-multiplexed switches or a pressure gauge. For example, if used as a sole in a shoe, the multiple pressure transducers would allow one to know the changes in a user&#39;s gait or foot pressures in different areas. 
     Furthermore, the cloth material  10  with separate conductive areas can be used as a switch matrix or a keyboard. That is, based on the level of the loop&#39;s resistance, the “ON” and the “OFF” switches can be formed. Also, when the user presses on the accessory  17 , the accessory  17  may change shapes under pressure, thereby allowing the user to know for certain that the accessory  17  has indeed been pressed. And when the user releases his finger from the accessory  17 , the user can feel that the accessory  17  has returned to its original shape due to its elasticity. In addition, the cloth material  10  with separate conductive areas can also be designed to have a single first conductive area  13  or a single extension part  16  and used as a single electric switch. A single extension part  16  may also be used with four first conductive areas, namely on the upper, lower, right and left, which can be used as a multi-staged electronic switch. In addition, whether the switch is ON or OFF may be determined by whether the amount of pressure applied exceeds a threshold. Using the same principle, we can design it to be a simple ON/OFF switch. Unlike a traditional accelerometers or gyroscope sensor that are too sensitive and cannot be worn or washed as a piece of clothing, a device of the invention can be worn or washed. When we use this as a gait analyzer or a long-term position change monitor, using wired or wireless means to send the signals of the various body positions as an ON/OFF signal (i.e., 0 or 1) to a care-taker, the care-taker will be able to monitor the present conditions of a user, such as whether the user has fallen, is in epileptic seizure, has suffered a stroke, or has any abnormal changes. At the same time, the 0,1 signals can be converted into 3D animations. If the user has suffered a stroke, we can use this gait analyzer or position change monitor to facilitate rehabilitation. At the same time, medical personnel can monitor the progress of the user. If the user is a healthy person, it can be used as an exercise guide, as in the tai-chi, where harmony between breathing and movement are emphasized. The ordinary person does not realize this, but if this sensor is used to monitor breathing and position, using 3D animation, it will show the changes in breathing which will be easy for the beginner to understand. The above examples show that the signals are all digital, not analog. 
     The structure of the cloth material  10  with separate conductive areas can also be variable. Please refer to  FIG. 3 : a cloth material  10   a  with separate conductive areas provided in this invention&#39;s second preferred example is almost the same as that of the previous example. The only difference is that the first conductive areas  13   a  on the first layer  12   a  form only on the surface of the first layer  12   a , and not penetrating the first layer  12   a . Each of the extension parts  16   a  all includes 2 connecting parts  18   a  connected to the accessory  17   a  and the first layer  12   a , making it easy to fix the accessory  17   a  in a specific location. The accessory  17   a  is made of an elastic material, while the cloth material may be a stretchable, woven cloth material, such as an elastic band. The extension parts  16   a  may include a non-conductive reinforcing thread  19   a , connected to accessory  17   a , enabling the accessory  17   a  to be stably fixed at a specific location. The reinforcing thread may include elastic material and is stretchable. 
     Since the first and the second conductive areas  13   a ,  172   a  are formed between the first layer  12   a  and the accessory  17   a , it can prevent short-circuit of the cloth layer  10   a  when the first layer  12   a  is folded or twisted. Furthermore, the accessory  17   a  can be made of a hard material, which can resist deformation, thereby maintaining a constant resistance in the electrical loop. Hence, the cloth material with separate conductive areas  10   a  can be used as a passive resistor. Such a cloth material  10   a  can be used as passive resistance components. 
     In addition, the accessory  17   a  may be made of an elastic material. Therefore, when a user stretches the first layer  12   a , due to the tension of the connecting wire  18   a , the accessory  17   a  will intimately contact the first electric conductance areas  13   a , resulting in a change in the resistance of the loop. Since the value of the resistance depends on the amount of pressure exerted by the user, hence the cloth material  10   a  with separate conductive areas can also be used as a strain gauge. 
     Furthermore, the cloth material  10   a  with separate conductive areas can also be made into a piece of clothing to be worn by a user. Due to the user&#39;s inhalation, exhalation, swallowing, or other body movements, the strain that is made to bear on the cloth material  10   a  can change. Therefore, this cloth material  10   a  can also be used as a position change sensor, a breathing sensor or a swallow sensor. 
     In addition, the two threads need not be separately attached to the accessory  17   a.  Instead, these may comprise a single connecting part  18   a  passing through the accessory  17   a.  In this case, the accessory  17   a  has a channel that allows the connecting part  18   a  to pass through. When external force or pressure is applied, the accessory  17   a  may move/slide freely, whether it comes into contact with the first conductible area  13   a  or not. With this embodiment, one can detect the relative change in position, relative change in movement speed, and relative change in acceleration between the accessory  17   a  and the first conductible area  13   a.    
     Furthermore, as shown in  FIG. 4 , on one side of the first layer  12   b  forms a fillister (trough)  121   b  to accommodate the accessory  17   b . The first conductive area  13   b  forms on the first layer  12   b  on the side opposite to the side facing the accessory  17   b , and location of the first conductive area  13   b  corresponds to the fillister  121   b . Both the first and second conductive areas  13   b ,  172   b  can conduct electricity. Therefore, they can form a capacitor. The control circuit  192   b  may include a capacitance meter for measuring the capacitance of the first and second conductive areas  13   b ,  172   b . Based on this, the control circuit  192   b  can trigger the output device  194   b  to send signals based on the capacitance levels as determined by the changes in distances between the first and second sensor areas  13   b ,  172   b.    
     In addition, because the accessory  17   b  may be located in the fillister  121 , it can effectively prevent the user from mistakenly touching the second sensor areas  172   b  of the accessory  17   b.    
     When the relative positions of the first and second sensor areas  13   b ,  172   b  are fixed, the cloth material  10   b  can also be used as passive capacitance material with a fixed (stable) capacitance. Also, one can change the surface areas or the space between the first and second conductive areas  13   b ,  172   b  to design different passive capacitance materials with different capacitance levels. For example, accessory  17   b  may include an insulator layer to increase the distance between the first and second conductive areas and to affect the capacitance. When the positions and shapes of the first and second conductive areas  13   b,    172   b  are changable, the cloth material  10   b  can also be used as variable capacitors. In addition, because the change in capacitance is related to the distance between the first and second conductive areas  13   b ,  172   b , one can analyze the change in the capacitance to learn the speed or acceleration of the accessory  17   b  relative to the first conductive area. Therefore, the cloth material  10   b  can also be used as a position change detector, speedometer or an acceleration detector. For example, when this cloth material is used in a shoe, it can be used to analyze thae user&#39;s gait and detect whether the user has fallen down. 
     Referring to  FIG. 5 , one can design the size of the extension part  16   c  and the accessory  17   c  so that they correspond to the fillister  121   c  of the first layer  12   c . Based on this, when the accessory  17   c  completely fits into the fillister  121   c , the surface of the cloth material  10   c  with separate conductive areas is maintained in a level position to increase its aesthetic value. In addition, the first conductive area  13   c  of the first layer  12   c  may be located inside the first layer  12   c . The surface of the cloth material  10   c  need not be flat; it can be a pile, fleece, or other compressible cloth material. The first conductive area  13   c  may be located on the bottom layer of the cloth material and forms a fillister. The accessory  17   c  may be located on the surface of the cloth material  10   c . When an external force is applied, the cloth material  10   c  is compressed, causing the first conductive area  13   c  to come into close to the second conductive area  172   c;  when external force disappears, it reverts to its original condition. Behind the accessory  17   c  may be a user&#39;s body. Therefore, when the direction of the force applied is from the cloth material  10   c  towards the accessory  17   c , the reaction produced may be large, and when the direction is from the accessory  17   c  towards the cloth material  10   c , the reaction may be small. Hence, the directions of the force applied can be distinguished. 
     Please refer to  FIG. 6 , the cloth material  10   d  with separate conductive areas provided in this invention&#39;s fifth preferred example is almost the same as that of the previous example. The only difference is that on top of its first layer  12   d  is a convexity (bump)  123   d.  The first layer  12   d  may have many ring-shaped first conductive areas  13   d  forming on top of the convexity  123   d . Its accessory  17   d  has 2 second conductive areas  172   d  which are made of a conductible material. The accessory  17   d  also has a concavity  174   b  which can accommodate the convexity  123   d . Based on mutual contact between the first and second conductive areas  13   b ,  172   b  on different locations, the first and second conductive areas  13   b,    172   b  can produce different signals to the control circuit. The cloth material  10   d  may be compressible. Its material can be rubber, vesicating material, sponge, spring, cotton, spandex, lycra, SBR (Styrene Butadiene Rubber), and foam-based material. The first conductive area of the first layer  12   d  does not need to be protruding, but may be flat. When external force is applied, the cloth material  10   d  is compressed, causing the first conductive area  13   c  to come into contact with the second conductive area  172   c;  when external force disappears, it reverts to its original condition. 
     Please refer to  FIG. 7 , the cloth material  10   e  with separate conductive areas provided in this invention&#39;s sixth preferred example is almost the same as that of the previous example. The only difference is that the first conductive area  13   e  of the first layer  12   e  is located on the inner sidewall of the fillister  121   e , and may contain several independent conductive areas (here it contains three conductive areas). The second conductive area  172   e  of the accessory  17   e  is dome-shaped. The control circuit  192   e  and the output device  194   e  are located on top of the accessory  17   e , and they are connected to the first conductive area  13   e  via the connecting wire  18   e . The accessory  17   e  contains only one conductive area  172 , whereas the cloth material  13   e  contains three independent conductive areas. 
     Please refer to  FIG. 8 , the cloth material  10   f  with separate conductive areas provided in this invention&#39;s seventh preferred example is almost the same as that of the previous example. The only difference is that there is a perforation  125   f  on its first layer  12   f . The first conductive area  13   f  of the first layer  12   f  is formed by sewing fine conductible wires around the perforation  12   f . The first layer  12   f  includes elastic material, for example elastic fibers or rubber. Therefore, the perforation  125   f  can be stretched, and the bigger the external force, the bigger is the diameter of the opening. The second conductive area  172   f  of the accessory  17   f  is shaped like strands, and is formed by sewing fine conductive wires on the accessory  17   f . The more the area of contact, the larger the external force is. The larger the diameter of the opening  125   f  is, the more contact area is between the first and second conductive areas  13   f  and  172   f . Therefore, this can be used as a pressure sensor or a strain sensor. The connecting part may be made of an elastic material, and through its elasticity we can increase its sensitivity. 
     Please refer to  FIG. 9 , the cloth material  10   g  with separate sensor areas provided in this invention&#39;s eighth preferred example includes a first layer  12   g , an extension part  16   g , a control circuit  192   g , and an output device  194   g . The first conductive area  13   g  of the first layer  12   g  is ring-shaped. The extension part  16   g  includes an accessory  17   g  and a connecting wire  18   g  which connects the accessory  17   g  and the non-conductive area  14   g  of the first layer  12   g . The second conductive area  172   g  of the accessory  17   g  is made of a magnetic material. The connecting wire  18   g  is non-conductive. Based on this, when the accessory  17   g  comes near or goes far from the first layer  12   g , the second conductive area  172   g  of the accessory  17   g  can cause the ring-shaped first conductive area  13   g  to produce a reactive electromotive force. The control circuit  192   g  can detect the reactive electromotive force, and can command the output device  194   g  to send signals based on it. In another word, the cloth material  10   g  with separate conductive areas can be used as a passive inductance material. 
     Please refer to  FIG. 10 , the cloth material  10   g  with separate conductive areas provided in this invention&#39;s ninth preferred example is almost the same as that of the previous example. The only difference is that the perforation  125   h  on its first layer  12   h  is triangle-shaped. The cloth material  10   g  may have 3 first conductive areas  13   h  forming individually on the 3 sides of the perforation  125   h . The accessory  17   h  forms a pyramid, and has 3 second conductive areas  172   h  forming individually on the 3 sides of the accessory  17   h.  The number of the connecting wires  18   h  is 3 as well. The accessory  17   h  of the pyramid can allow the user to conveniently slip it into the perforation  125   h . One can design the perforation  125   h  to be smaller in size to increase the market acceptance of the cloth material  10   h . One can have one or more electric current or signal transmitting devices. The connecting part may be composed of an elastic material. So, when the accessory  17   h  is pushed into the perforation  125   h , the influence exerted by the external force on the two is minimal. 
     Furthermore, due to the fact that the perforation  125   h  and the accessory  17   h  are non-rounded, they can guide a user to first rotate the accessory  17   h  to an appropriate angle before inserting it into the perforation  125   h , so that the second conductive area  172   h  can more accurately contact the first conductive area  13 . Therefore, a single accessory can have many different conductive areas that interact with the different conductive regions in the first conductive areas of the cloth material  10   h.    
     Please refer to  FIG. 11 . A cloth material  10   k  with separate conductive areas provided in this invention&#39;s tenth preferred example is almost the same as that of the previous example. The only difference is that the first conductive area  13   k  of the first layer  12   k  is formed by sewing conductible fine wires along the perforation  125   k  in a winding, helical pattern. The accessory  17   k  of the extension part  16   k  is made of a magnetic material, which forms the second conductive areas  17   k . The accessory  17   k  is cylindrical in shape. The connecting wire  18   k  of the extension part  16   k  is made of a metallic material, and winds around the accessory  17   k  helically like a coiled spring. Based on this, when there is electric current flowing in the connecting wire  18   k , and when the accessory  17   k  is far away from or near the perforation  125   k , the accessory  17   k  will cause the first conductive area  13   k  to produce a reactive electromotive force. Since the accessory  17   k  is cylindrical in shape, it is easy to design and manufacture. Because the accessory has the special characteristics of a coiled spring, when the external force disappears, it still oscillates several times, transforming kinetic energy (such as energy from exercise) into electrical energy and stores it. 
     Please refer to  FIG. 12 , the cloth material  20  with separate conductive areas provided in this invention&#39;s eleventh preferred example includes a first layer  22 , an extension part  25 , a second layer  29 , a control circuit (not shown), and an output device (not shown). The connecting part  27  of the extension part  25  is made of a metallic material, and it connects the accessory  26  and the second layer  29 . The control circuit is also connected to the second conductive area  262  of the accessory  26  via the connecting part  27 . In addition, the extension part  25  includes a non-conductive reinforcement wire  28  which is individually connected to the accessory  26  and the second layer  29 , making the accessory  26  to be more securely fixed to the second layer  29 . The reinforcement wire can incorporate an elastic material and have flexibility. 
     Please refer to  FIG. 13 , a cloth material  30  with separate conductive areas provided in this invention&#39;s twelfth preferred example is almost the same as that of the previous example. The only difference is that its accessory  36  is formed by sewing connecting wires  37  to the second layer  39 . Similarly, when the first layer cloth material  30 , which is nearest to the user&#39;s body, is pressed against the second layer of the accessory  36 , a change in reaction may ne smaller than if the same force is applied on the second layer of the accessory  36  against the first layer cloth material  30  towards the user&#39;s body, because of behind the first layer cloth material  30  is the user&#39;s body. Therefore, the directions of force applied can be discerned. 
     Based on the above-mentioned structure, a manufacturer may use the first layer  32  and the second layer  39  to make a pair of under pants and a pair of trousers, respectively, to be worn by a user. The first and second conductive areas  33 ,  362  may be placed near the user&#39;s abdominal area. Based on this, the user can cause the first  33  and second conductive areas  362  to contact tightly by breathing deeply or tightening his abdominal wall, which causes the resistance level in the loop to decrease. Then, the output device may send a signal. Similarly, the control circuit may also cause the output device to send a signal by monitoring the change in capacitance level produced by the first  33  and second conductive areas  362 . Furthermore, the first conductive area  33  may be designed to be ring-shaped so that the control circuit can command the output device to send a signal based on the reactive electromotive force formed in the first conductive area  33 . When the first layer  32  is made into an undergarment, it can also act as an electrode. When the second layer is made into an outer garment, both the control circuit and the output device may be located on the outer garment. Therefore, it can read a user&#39;s ECG and change in respiration. 
     In addition, the first layer  32  can be designed into a chair, and the second layer  39  can be made into a shirt or a pair of pants for a user to wear. Based on this, the user can change his sitting position based on the correctness of the pressured part. The first layer  32  can also be designed into a surface of a bed sheet, and the second layer  39  can be made into a shirt or a pair of pants for the patient with chronic disease to wear. Through this, the caretaker can help turn the patient over at the proper time based on the location of the pressured part and the length of time that it has been under pressure, or know if the patient has fallen from his bed. In the beginning, the first and the second conductive areas may not conduct any current, unless compressed by an external force, as in lying down, where it becomes conductive. Therefore, this can save a lot of energy. Furthermore, the signals may be digital (instead of analog), avoiding the need for complicated signal processing. 
     Based on the essence of this invention, the structure of a cloth material with separate conductive areas can have many variations. Now please refer to  FIG. 14 . A cloth material  40  with separate conductive areas provided in this invention&#39;s thirteenth preferred example similarly includes a first layer  42 , an extension part  45 , a second layer  49 , a control circuit (not shown), and an output device (not shown). Both the first layer  42  and the second layer  49  may belong to ends of a single piece of cloth material. Like middle part of a shirt or cuffs of a suit, these two layers may be on two ends, one end containing the button, the other end containing the buttonhole. The first layer  42  may have a perforation  421 , multiple conductive fine wires  43  and a non-sensor area  44 . The conductive fine wires  43  are sewn along the perforation  421  and form the first conductive areas  43  on the first layer  42 . The first conductive areas  43  (acting as the conductible fine wire  43  simultaneously) are separate from one another. The non-conductive area  44  is formed around the first conductive area  43 . The extension part  45  has an accessory  46  and two connecting parts  47 . The accessory  46  is in the form of a button and is made of an insulated material. It is sewn into the second layer  49  via the two connecting parts  47 . The second layer  49  is made of an elastic material, such as a piece of elastic band, spandex, SBR, Styrene Butadiene Rubber, or a foam-based cotton material. The two connecting parts  47  are made of a conductive material, and they form the second conductive areas  47  of the extension part  45  (acting as the connecting part  47  simultaneously). The two connecting parts  47  also pass through the perforation  421  of the first layer  42 . The first layer  42  is located between the accessory  46  and the second layer  49 . Based on these, a user can pull and drag the first layer  42  and the second layer  49  in opposite direction, as in breathing or bending the wrist. The pulling or dragging is limited to the direction of the perforation  421 , causing the second layer  49  to carry the button  46 , to move along the perforation  421 . Based on the connecting parts  47  coming into contact with the first conductive areas  43  at different locations, the control circuit can control the output device to send different signals. If the connecting part is made of a non-conductive material, while the button  46  is made of a conductive material, the button may replace the connecting part as the second conductive areas, which may achieve similar results. That is, the cloth material  40  with separate conductive areas may be used as a signal-producing device or as a strain gauge. For example, the first layer  42  may be a pair of pants, while the second layer  49  is a shoulder strap (a suspender). The buttons  46  are on the pants. Therefore, the changes in conduct of the user will cause similar changes in the second layer shoulder strap  49 . Therefore, it can detect different digital signals produced by the first conductive area  43  and the second conductive area  47 . 
     In addition, the circumference around the connecting parts  47  may be clad with an insulated material. Based on this, the control circuit can also cause the output device to send a signal by monitoring the changes in capacitance levels produced by the connecting parts  47  and the first conductive area  43 . 
     Now please refer to  FIG. 15 , a cloth material  50  with separate conductive areas provided in this invention&#39;s fourteenth preferred example is almost the same as that of the previous thirteenth example. They both include a first layer  52 , a non-sensor area  54 , an extension part  55 , a second layer  59 , a control circuit (not shown), and an output device (not shown). The only difference is that there are one or more independent first conductive areas  53  on the first layer  52 , which may be round-shaped and separated from the rim of the perforation  521  by a pre-determined distance. The accessory  56  of the extension part  55  is made of a conductible material and is also in the form of a button  56  to form the second conductive area  56  of the extension part  55 . The extension part  55  also includes an electronic part  561  located on the button  56 , which is electrically connected to the connecting part  57 . The electronic part  561  can include an integrated circuit (IC), a light emitting diode (LED), a sensor device, antenna, speakers, microphone, a resistor, a capacitor, an inductor or a battery. 
     A user can, as in breathing or swallowing, apply the pressure on the button  56  in order to tilt it and let it come into contact with the first conductive areas  53  on the first layer  52 , forming a pressure detector, which can detect where the direction (up, down, left or right)of the pressure is coming from. Also, one can clad a layer of an insulated material on the bottom part of the button  56 , for example plastic, so that the user can apply pressure on the button  56  to change the conductance values produced by the first and second conductive areas  53 ,  56 . 
     Now please refer to  FIG. 16 , a cloth material  60  with separate conductive areas provided in this invention&#39;s fifteenth preferred example is almost the same as that of the previous thirteenth example. The only difference is that the extension part  65  also includes a header  68  located in the accessory  66 , and an electronic part  661  located in the header  68 . The electronic part  661  is electrically connected to the connecting wire  67 . The accessory  66  is made of a conductible material and is also in the form of a button  66 . It also forms the second conductive area  66  of the extension part  65 . The header  68  is made of an insulated material, thereby preventing accidental electrocution when the user touches the accessory  66 . 
     Now please refer to  FIG. 17 , a cloth material  70  with separate conductive areas provided in this invention&#39;s sixteenth preferred example is almost the same as that of the previous example. They both include a first layer  72 , non-sensor area  74 , an extension part  75 , a second layer  79 , a control circuit (not shown), and an output device (not shown). The first layer  72  has a perforation  721  and one first conductive area  73 . Conductive fine wires are sewn along the perforation  721  to form the first conductive areas  73 , at a location corresponding to the accessory  76 ; however, the two are not in contact with each other. The first conductive area is separated from the rim of the perforation  721  by a pre-determined distance. The connecting part  77  of the extension part  75  is made of a non-metallic material; the accessory  76  is made of a metallic material. When the second conductive area  76  is moved, the conductance values produced by the first and second conductive areas  73 ,  76  will change. The control circuit may then cause the output device to send a signal based on the changes in capacitance levels. The cloth material  70  with separate conductive areas that can automatically change its condition when external force is applied can be so designed that the first conductive area  73  forms at the rim of the perforation  721  of the first layer  72 , and matches up with the outer part of the connecting part  77 , which is clad with an insulated material and is the second conductive area. 
     Please refer to  FIG. 18 , a cloth material  80  with separate conductive areas provided in this invention&#39;s seventeenth preferred example has the same non-conductive area  84 , first layer  87 , and a second layer  82  all located on the cloth layer  80 . There is a first conductive area  81 , a control circuit (not shown), and an output device (not shown) on the first layer  87 . The only difference is that its second layer  82  has a ringed hook as the connecting part  83  which is elastic. The accessory  88  is sewn onto the second layer  82 , forming the second conductive area. This accessory  88  is divided into three second conductive areas. There is button  86  on top of the first layer  87 . Based on this, the ringed hook  83  can be put around the button  86 . Different degrees of external force will produce different degrees of tension, causing the first conductive area to come into contact with the three different second conductive areas, thereby producing different signals. For example, if a user swallows or moves, he will cause a change in the accessory  88  and the first conductive area. 
     Please refer to  FIG. 19 , a cloth material  90  with separate conductive areas provided in this invention&#39;s eighteenth preferred example has the same one first layer  92 , non-conductive area  94 , two extension parts  95 , one second layer  99 , one control circuit (not shown), and an output device (not shown). The first layer  92  includes two female snap-on buttons  921 , each being sewn onto the non-conductive area  94  using three conductive fine wires  93 . The snap-on buttons  921  are made of an insulated material. The conductive fine wires  93  form three first conductive areas  93  (also functioning as conductive fine wires  93 ) of the first layer  92 . The three conductive fine wires  93  can use other conductive material as substitute, and are electrically connected with the control circuit. The two extension parts  95  each contains one accessory  96  and three connecting part wires  97 . The accessories  96  are sewn onto the second layer  99  via the extension parts  97 . The accessories  96  are male snapped-on buttons and are made of an insulated material. The accessories  96  may separately be incorporated into the female buttons  921 . The connecting parts  97  each form a second conductive area  97  (also functioning as a connecting part  97 ) of the extension part  95 . Based on these, a user can button together a male portion  96  and a female portion  921  of the buttons, causing the first conductive areas  93  to come into contact with the second conductive areas  97 , forming an electrical loop. Each pair of the male portion  96  and the female portion  921  of the buttons may conduct three different levels electrical currents or signals. Furthermore, the number of the male portions  96  and female portions  921  of the buttons may be one or more than three. The number of the male portions  96  of the buttons can be more than or less than that of the female portions  921 . 
     Please refer to  FIG. 20 , a cloth material  90   a  with separate conductive areas provided in this invention&#39;s nineteenth preferred example has the same one first layer  92   a , one non-conductive area  94   a , one extension parts  95   a , one second layer  99   a , one control circuit (not shown), and an output device (not shown). The first layer  92   a  has one clip hook  93   a  which is made of a conductive material and forms a first conductive area  93   a  on the first layer  92   a.  The extension part  95   a  has an accessory  96  that is sewn onto the second layer  99   a  using connecting wires. The accessory  96   a  is made of a conductive material and forms the second conductive area  96   a  (also functioning as the accessory  96   a ) of the extension part  95   a . The connecting part  97   a  is made of a metallic material. Based on these, the clip hook  93   a  can be clipped onto the accessory  96   a , forming an electrical loop. 
     Please refer to  FIG. 21 , a cloth material  11  with separate conductive areas provided in this invention&#39;s twentieth preferred example is almost the same as that of the twelfth example. The extension part  115  includes: an accessory  116  and a connecting part  117 ; the accessory is sewn onto the second layer  119  via the connecting part  117 . The first layer cloth material  112  includes: a non-conductive area  114  and a first conductive area  113 . The only difference is that the first conductive area  113  is composed of a wire-strip, and inside the accessory  116 , there is a channel  118  that allows the first conductive area  113  to freely pass through. On the wire-strip, there are several first conductive areas. The accessory also has the second conductive areas  1162 . 
     Based on the above structure, a manufacturer can individually make the first layer  112  and the second layer  119  into an upper garment and a sleeve for a user to wear, placing the first and second conductive areas  113 , 1162  near the armpit of the user. Based on this, the user can cause the first conductive area  113  and the second conductive area  1162  to be in close contact with each other by moving his upper arm, thereby lowering the resistance of the output device, and sending out signals. Similarly, the control circuit can also cause the output device to send out signals and sense the angle and speed of movement of the arm&#39;s movement by sensing the changes in the capacitance produced by the first conductive area  113  and the second conductive area  1162 . 
     Please refer to  FIG. 22 . In accordance with the invention, cloth materials with separate conductive areas that can automatically change its condition when external force is applied work as follows: 
     When the first and the second conductive areas are influenced by an outside force, the change in sensing is illustrated in  FIG. 22 : the signals may have noise and may jump around. As shown in  FIG. 23 , the sensing process works like this: First one sets an initial determining value. In the absence of an outside force, the accessory and the cloth material area may be separated. It may be referred to as the “high” (or open) state. The “initial determining value” may be set to the highest or a high value. At the same time, the sampling rate is set, for example, once per second. Finally, one sets a “threshold value A” of the signal detector. For example, one may set the threshold values A to one-half the highest signal detected. Then, one starts to collect the signals detected by the accessories and the cloth materials at regular intervals as the “detected signal value B.” If a “detected signal value B” is≧“threshold value A,” then one adds 1 to the initial determining value, and at the same time initiates an evaluation process. 
     This evaluation will ascertain whether or not the “determining value” is the highest possible determining value expected. If it is the highest determining value or even higher, then the highest determining value is set as the “determining value.” Then, one can conclude that the accessory and the cloth material are still not in contact with each other (in a high or open state). However, if the determining value is not the highest determining value, or does not exceed the highest determining value, then one assesses whether or not this determining value is higher than the expected determining value. If it is, then one concludes that the accessory and the cloth material are still not in contact with each other (still in a high or open state). If it is not, then one will repeat the evaluation process, using the determining value plus 1 as the “determining value.” 
     If the “detected signal value B” is less than the “threshold value A,” then 1 will be subtracted from the determining value, at the same time initiating an evaluation process. This evaluation will ascertain whether or not the “determining value” is the lowest possible determining value forecasted. If it is, the lowest value or even lower, then one will accept it as the “determining value.” Then, one concludes that the accessory and the cloth material are in contact with each other (in a low or short state). However, if it is higher than the lowest determining value, then one will determine whether or not this determining value is lower than the forecasted low determining value. If it is, then one concludes that the accessory and the cloth material are in contact with each other (in a low or short state). If it is not, then one will repeat the evaluation process, using the determining value minus 1 as the “determining value.” 
     Explaining further, the determining factor of the wave form of the accessory and the cloth material is obtained by first getting the determining value after getting samples and putting it in the counter, as shown in  FIG. 24 , going over the boundary. And in the counter, there are the lowest determining value, low determining value, high determining value, and the highest determining value. Its wave form will be in between the lowest and the highest determining values, not lower than the lowest determining value and not higher than the highest determining value. When it reaches the highest determining value, we can ascertain that the accessory and the cloth material have been separated (in a high or open state). On the other hand, when it reaches the lowest determining value, we can ascertain that the accessory and the cloth material are in contact with each other (in a low or short state). 
     Signals of  FIG. 22 , after processing the sense connection status using the method, are shown in  FIG. 25 . One can eliminate false signals and oscillating interference and obtain a standard which can be easily applied and completed, not needing any complicated calculations. It is an energy-saving, down-sized and wearable piece of innovation. 
     The above description clearly explains, with the aid of drawings, the advantages and applied examples of this invention. However, one skilled in the art would know that without extending beyond the scope of this invention, others can modify or change its model, even substituting other materials for its component parts. For example, for purposes of explaining, some embodiments of the invention have illustrated with a round-shaped accessory. However, one would understand that this can be substituted with other shapes of accessories. Therefore, the shapes of the conductive areas in the cloth materials should not limit the scope of this invention. Therefore, the invention is not restricted or limited to the preferred examples. Instead, this invention includes all examples that falls within the scope of its claimed rights. 
     On the basis of the essence of this invention, the structure of the cloth material equipped with separate conductive areas can have many variations. For example, the control circuit can be programmed with a time threshold (ex: 3 seconds). When the time of the electrical conduction between the first and second conductive areas exceeds the time threshold, the control circuit may command the output device to produce a signal, thereby preventing contact by mistake. Referring to the various changes of the above, the scope must be covered by this invention&#39;s patent application without exception.
