A textile electrode kit mounted to the clothing includes a contact-type electrode or a non-contact electrode, and the textile electrode kit may be mounted to a clothing having a lower fixed member configured to reduce a motion artifact and a partially three-dimensional clothing structure by means of sewing. On occasions, the textile electrode kit having a non-contact electrode may be inserted into and used in an electrode-mounting pocket or an electrode-mounting tunnel formed at the clothing. The textile electrode kit of the present disclosure may detect various kinds of bio signals such as a heart activity signal, an electrocardiogram (ECG) signal, an electromyogram signal, a breathing signal or the like.
This application claims priority under 35 U.S.C. §119 to Korean Patent Application No, 10-2013-0106380 filed on Sep. 5, 2013 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety,
The following disclosure relates to clothing with a minimized motion artifact to which a textile electrode kit is mounted, which includes a textile electrode kit having a conductive textile-based bio signal measurement sensor, and a clothing structure configured to stably detect a bio signal such as a heart activity signal and an electrocardiogram (ECG) of a subject person in a non-restrictive and non-invasive way with a minimized motion artifact during ordinary activities by mounting the textile electrode kit to the clothing.
A patient suffering from a chronic disease such as a cardiac disease should monitor his/her health state, and for this, the patient should directly visit a hospital inconveniently with great costs.
In case of existing sensors, accuracy of heart activity signal measurement deteriorates if a contact point between an electrode and a human body deviates due to a motion of a user. In addition, such existing sensors are inconvenient since they should be mounted to excessively press a human body for a long time. These sensors are not suitable for continuous measurement at daily life.
Korean Patent Registration No. 10-0863064 or the like proposes a bio-signal measurement clothing to which an electrode is mounted. This clothing includes at least one electrode integrally coupled to the inner side of the clothing and coming into contact with the skin surface to detect a bio signal. However, if a human body moves while the electrode integrated with the clothing is detecting a bio signal in contact with the human body, a signal with much motion artifact is detected, which deteriorates accuracy and precision in analysis of the detected bio signal. In other words, even though bio signal may be detected non-restrictively, non-Invasively and continuously by using the existing clothing integrated with an electrode, since a gap is inevitably present between the electrode and the human body due to bent portions of the human body, if the human body moves, the electrode moves accordingly and thus the motion artifact increases as much due to the gap.
Therefore, there is needed clothing with a minimized motion artifact to which a textile electrode kit is mounted, which may measure a bio signal through clothing in a non-restrictive, non-invasive and continuous way anytime and anywhere while minimizing a measurement artifact caused by a motion of the user.
In the textile electrode kit of the present disclosure, a non-contact electrode as well as a contact-type electrode, which has been widely used in the art from the past, is used.
In the present disclosure, as a non-contact electrode, a coil-type magnetic induction sensor is used. In relation to the coil-type magnetic induction sensor, the inventors of the present disclosure have a patent right for Korean Patent Registration No. 10-1302600 which is directed to a conductive textile-based bio signal measurement sensor.
FIG. 1 is a diagram for illustrating a configuration for detecting a volume change according to a change of inductance by using the conductive textile-based bio-signal measurement sensor disclosed in Korean Patent Registration No. 10-1302600.
An inductor-type bio-signal measurement sensor 40 is mounted, and a signal detector 30 is mounted to an outer side of the inductor-type bio-signal measurement sensor. The detector includes an oscillating unit 50 and a demodulating unit 70.
The oscillating unit 50 is composed of an oscillation circuit having L and C to transmit a vibration signal to the inductor-type bio-signal measurement sensor 40.
The inductor-type bio-signal measurement sensor 40 is configured to maximize sensitivity by disposing a ferromagnetic substance core capable of focusing a magnetic flux on a center portion of the coil. In other words, a volume of interest (VOI) may cause a temporal variation, formed by a geometric structure of a coil sensor, namely influenced by a magnetic force, and the conductive textile-based bio-signal measurement sensor 40 senses a change of eddy current caused by electric conductivity of a substance located in the volume.
If the inductor-type bio-signal measurement sensor 40 receives a vibration signal, a magnetic field of a time-varying function is formed in a living body in the volume of interest (VOI) 20, and the generated magnetic field creates an eddy current in the substance. The inductance of the sensor is influenced by a movement of a detection target. Therefore, a vibration signal of the heart muscle causes a change of inductance of the coil, and this signal is transmitted through the oscillating unit 50 to the demodulating unit 70.
The demodulating unit 70 removes a vibration signal applied to the inductor-type bio signal measurement sensor 40 from the above signal to detect only a bio signal.
In detail, a magnetic field is formed by a current minutely flowing on the coil of the inductor-type bio-signal measurement sensor 40. The magnetic field varying according to time induces an eddy current in a detection target (or, in a human body), and the formed induced current generates a minute magnetic field in a direction opposite to the magnetic field formed at the coil. The change of the magnetic field of the coil of the inductor-type bio-signal measurement sensor 40 results in a variation of the inductance (the induced magnetic field) of the coil. To detect the variation, the oscillating unit 50 serving as an oscillation circuit is provided to regard the coil of the inductor-type bio-signal measurement sensor 40 as an inductor circuit, and in this case, a frequency modulation representing a variation of a frequency of an oscillator exhibited due to a movement of a detection target (in a human body). As one of detection methods, the demodulating unit 70 may trace a modulated frequency by using a phase-locked loop (PLL). If this frequency demodulation is used, a movement of the detection target is exhibited as a PLL output, which allows a movement of the heart to be measured.
An embodiment of the present disclosure is directed to providing clothing with a minimized motion artifact to which a textile electrode kit is mounted, which includes a textile electrode kit composed of a conductive textile-based bio signal measurement sensor or the like, and a clothing structure configured to stably detect a bio signal such as a heart activity signal and an electrocardiogram (ECG) of a subject person in a non-restrictive and non-invasive way with a minimized motion artifact during ordinary activities by mounting the textile electrode kit to the clothing.

In FIG. 2 a, a front center band 211 and a back center band 231 are connected through right and left elastic members 221. The front center band 211 has a chest center elastic member 219 at a center portion, a left front center band 215 at a left side of the chest center elastic member 219, and a right front center band 216 at a right side of the chest center elastic member 219. A front upper central dart 227 which is a vertical cut line formed from a neckline center of a front sheet to a lower end of the front center band 211, namely a lower end of the chest center elastic member 219, is provided, and a back lower central dart 228 which is a vertical cut line formed from a center of the lower end of the back center band 231 to the waist portion is provided. On occasions, a rear upper center dart (not shown) may also be provided at an upper portion of the rear sheet, similar to the front upper central dart 227.
The elastic member 221 is located below right and left armpits or right and left chests, connects the front center band 211 to the back center band 231, and is made of an elastic material. For this reason, even though the front center band 211 and the back center band 231 made of non-elastic material are provided at the front and rear sheets, easier motion may be ensured.
In the present disclosure, the elastic material means a material with good elasticity, opposite to an non-elastic property, for example a knitted textile containing at least 3% of polyurethane (spandex), a knitted fabric such as rib organization or accordion organization, an embroidered fabric containing at least 5% of elastic thread, an elastic band, rubber bands with various widths, smocking or the like.
The elastic member 221 may be an under-armpit elastic member 221 a disposed below the right and left armpits as shown in Portion (a) of FIG. 2 a or an under-chest elastic member 221 b disposed below the right and left chests as shown in (b) of FIG. 2 a. The elastic member 211 is made of highly-stretchable material or elastic material.
The under-armpit elastic member 221 a may have a width (vertical) of at least 5 cm to 10 cm and a breadth (horizontal) of ⅛ of a minimum chest size to ¼ of a maximum chest size, and the breadth and width (vertical) of the under-armpit elastic member 221 a may vary depending on the material. The under-armpit elastic member 221 a is located at a point where a bust line crosses with a side seam.
The under-chest elastic member 221 b may be particularly disposed below both breasts of a woman, for clothing of a woman. This under-chest elastic member 221 b is disposed between the side seams and the center of breasts and is located in consideration of a body type of a wearer. At this time, a neckline of the woman clothing may have a halter structure.
The front center band 211 crosses the chest portion at the front sheet and is connected from a lower portion of the left armpit to a lower portion of the right armpit with a band shape. In case of a woman clothing, the front center band 211 may extend to the neckline so as to be disposed above the breasts.
A left front center band 215, a right front center band 216 and a chest center elastic member 219 are provided.
One of the left front center band 215 is mounted to the left elastic member 221, and the other end is mounted to one end of the chest center elastic member 219 through a lower portion of the left chest.
One end of the right front center band 216 is mounted to the right elastic member 221, and the other end is mounted to the other end of the chest center elastic member 219 through a lower portion of the right chest.
The left front center band 215, the right front center band 216 and the back center band 231 are made of non-elastic or low-elastic material in regions used for mounting electrodes, and the other regions are made of elastic material so that the electrodes are shaken as small as possible due to a movement of a human body.
The front center band 211 and the back center band 231 may have a width (vertical) of at least 5 cm to 10 cm and a breadth (horizontal) of ¼ of a minimum chest size to ¾ of a maximum chest size and be located at a bust line. In particular, the front center band 211 is installed to cover a point located at a left side by 3 to 5 cm from a cross point of the bust line and the front center.
The front upper central dart 227 is formed to be fit (closely adhered) to a chest surface according to a three-dimensional structure of the cleavage between breasts. In particular, since a top clothing is spaced more at the cleavage portion in comparison to other portions, the chest center elastic member 219 made of an elastic material is provided, and the front upper central dart 227 passes through the center portion of the chest center elastic member 219 so as to be fit to the body (the chest) and ensure more convenient motion.
The back center band 231 has a band shape, and one end of the back center band 231 is mounted to the left elastic member 221 at the rear sheet, and the other end is mounted to the right elastic member 221, across a back center portion.
The back lower central dart 228 is provided to be fit (closely adhered) to a waste surface according to a three-dimensional structure of a spinal curvature of the waist portion in consideration of a concave portion along the spine between the back lower portion and the waste.
Generally, a dart is formed by folding a planar fabric as in a clothing pattern to give a three-dimensional feeling, and the front upper central dart 227 and the back lower central dart 228 may have different locations and sizes according to a portion which demands close adhesion between the clothing and the surface of the human body. Thus, the front upper central dart 227 and the back lower central dart 228 are fabricated suitable for various curves such as cleavage or spine.
Meanwhile, at least one of the front central band 221 and the back central band 231 may be formed at an inner side surface of the clothing, namely at a surface which comes into contact with the skin. Therefore, the front central band 221 and the back central band 231 do not outstand, and electrodes may be disposed at the front central band 221 or the back central band 231 to make direct contact with the skin.
In FIG. 2 b, the back center band 231, the back lower central dart 228 and the elastic member 221 are substantially identical to those of FIG. 2 a.
In FIG. 2 b, the front center band 211 and the back center band 231 are connected through the right and left elastic members 221 and includes a first vertical support unit 205 vertically extending from the neckline to an upper portion of the front center band 211 and a second vertical support unit 206 vertically extending from a lower portion of the front center band 211 to the front lower end 209.
Here, the front center band 211 is made of non-elastic material, and one end of the front center band 211 is mounted to one end of the left elastic member 221, and the other end is mounted to one end of the right elastic member 221.
The back center band 231 is made of non-elastic material, and one end of the back center band 231 is connected to the other end of the left elastic member 221, and the other end is mounted to the other end of the right elastic member 221, across the back center portion.
The front center band 211 and the back center band 231 are used for mounting electrodes and are configured to be shaken as small as possible due to a movement of a human body.
The first vertical support unit 205 is made of non-elastic material and supports the front center band 211 to reduce a movement of the front center band 211 due to a movement of a human body together with the second vertical support unit 206. The first vertical support unit 205 is vertically mounted from an intermediate portion between a neckline center of the front sheet and a point where the neckline meets a shoulder line to an upper portion of the front center band 211.
The second vertical support unit 206 is made of non-elastic material and supports the front center band 211 to reduce a movement of the front center band 211 due to a movement of a human body together with the first vertical support unit 205. The second vertical support unit 206 is vertically mounted from a corresponding portion of the first vertical support unit 205 (an intermediate portion between a lower center of the front center band 211 and one end or the other end of the front center band 211) to the front lower end 209, at a lower portion of the front center band 211.
The first vertical support unit 205 and the second vertical support unit 206 are made of non-elastic material or low-elastic material and have a width (vertical) from the front neckline to a horizontal line. The width varies depending on a human body. The breadth (horizontal) is 2 cm to 10 cm and varies depending on a size of an attached electrode. The first vertical support unit 205 and the second vertical support unit 206 are located to form a straight line with a center of an electrode mounted to the front center band 211.
The front center band 211, the back center band 231, the first vertical support unit 205 and the second vertical support unit 206 are made of non-elastic material, and other portions are made of elastic material.
On occasions, a third vertical support unit (not shown) may be further provided at the rear sheet to correspond to the first vertical support unit 205 of the front sheet, and a fourth vertical support (not shown) may be further provided at the rear sheet to correspond to the second vertical support unit 206 of the front sheet.
Portion (a) of FIG. 2 c is substantially identical to FIG. 2 h from which the second vertical support unit 206 is excluded, and thus is not described in detail here.
Portion (b) of FIG. 2 c includes all components of FIG. 2 b and further includes a front abdominal band 241 and a waste sideline elastic members 229. On occasions, a back abdominal band (not shown) may also be further provided.
Here, the waste sideline elastic member 229 is made of elastic material (for example, an elastic band) and mounted to side seams of the right and left waist portion to connect the front abdominal band 241 and the back center band (not shown) or connect the front abdominal band 241 to the rear sheet so as to ensure easily motion even though the front abdominal band 241 made of non-elastic material is provided.
The front abdominal band 241 is made of non-elastic material and disposed at the front sheet of the clothing with a band shape. One end of the front abdominal band 241 is mounted to one end of the left waste sideline elastic member 229, and the other end is mounted to one end of the right waste sideline elastic member 229, across the abdominal area.
The back abdominal band (not shown) is made of non-elastic material and disposed at the rear sheet of the clothing with a band shape. One end of the back abdominal band is mounted to the other end of the left waste sideline elastic member 229, and the other end is mounted to the other end of the right waste sideline elastic member 229, across the back waist portion.
Portion (c) of FIG. 2 c is substantially identical to Portion (b) of FIG. 2 c from which the front center band 211, the back center band 231 and the under-armpit elastic member 221 are excluded, and all components of Portion (c) of FIG. 2 c are identical to those of Portion (b) of FIG. 2 c and thus not described in detail here.
In the present disclosure, as shown in FIGS. 2 a to 2 c, contact-type electrodes or non-contact electrodes may be mounted to the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown) to detect a bio signal. If a contact-type electrode is mounted, the contact-type electrode may be mounted to a portion of the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown), which comes into contact with the skin. If a non-contact electrode is mounted, the non-contact electrode may be mounted to an outer surface of the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown) (namely, a surface opposite to the surface in contact with the human body).
In addition, in FIGS. 2 a to 2 c, a pocket or tunnel may be provided at the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown), and an electrode may be mounted in the pocket or the tunnel to detect a bio signal.
In FIGS. 2 a to 2 c, the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown) are depicted as a structure for mounting an electrode, but the present disclosure is not limited thereto, and the present disclosure may have various structures for mounting an electrode.
FIG. 2 d is a diagram for illustrating a decrease of a motion artifact according to a vertical movement (upper and lower movement) at a horizontal band in the present disclosure.
If a horizontal band located horizontally at the clothing and made of non-elastic material like the front center band 211, the back center band 231, the front abdominal band 241 and the back abdominal band (not shown) is mounted, since the horizontal band is continuous in a horizontal direction, a horizontal movement of a human body (a horizontal vector) is transferred as it is. In other words, a motion artifact according to the horizontal movement of a human body (namely, right and left movement) (a horizontal vector) is transferred as it is.
However, the lop surface 194 and the bottom surface 195 of the horizontal band are connected to the elastic material, respectively. Even though the top surface 194 is connected to the upper portion of the top surface 194, made of elastic material, the connection portion is a discontinuous portion where the material of the top surface 194 and the material of the upper portion of the top surface 194 are not continuous. Similarly, the connection portion connecting the bottom surface 195 to the lower portion of the bottom surface 195, made of elastic material, is a discontinuous portion where the material of the bottom surface 195 and the material of the lower portion of the bottom surface 195 are not continuous any more.
A vertical movement of a human body (a vertical vector) is substantially not transferred when meeting the discontinuous portion. Therefore, a motion artifact according to the vertical movement of a human body (namely, upper and lower movement) (a vertical vector) is reduced.
FIG. 2 e is a diagram for illustrating a decrease of a motion artifact according to a horizontal movement (right and left movement) at a vertical band in the present disclosure.
If a vertical band located vertically at the clothing and made of non-elastic material like the first vertical support unit 205 and the second vertical support unit 206 is mounted, since the vertical band is continuous in a vertical direction, a vertical movement of a human body (vertical vector) is transferred as it is. In other words, a motion artifact according to the vertical movement of a human body (namely, upper and lower movement) (a vertical vector) is transferred as it is.
However, the left side surface 196 and the right side surface 197 of the vertical band are connected to the elastic material, respectively. Even though the left side surface 196 is connected to the left side portion of the left side surface 196, made of elastic material, the connection portion is a discontinuous portion where the material of the left side surface 196 and the material of the left side portion of the left side surface 196 are not continuous. Similarly, the connection portion connecting the right side surface 197 to the right side portion of the right side surface 197, made of elastic material, is a discontinuous portion where the material of the right side surface 197 and the material of the right side surface of the right side surface 197 are not continuous any more.
A horizontal movement of a human body (a horizontal vector) is substantially not transferred when meeting the discontinuous portion. Therefore, a motion artifact according to the horizontal movement of a human body (namely, right and left movement) (a horizontal vector) is reduced.
FIG. 2 f is a diagram for illustrating a decrease of a motion artifact according to a horizontal movement (right and left movement) at a dart vertically located in the present disclosure.
If the clothing has a dart located in a length direction (a longitudinal direction), both sides of the dart are discontinuous. In other words, since the dart is located vertically, a horizontal movement of a human body is reduced when colliding with the dart. However, a vertical movement of a human body is transferred as it is since there is no obstacle. Therefore, if a dart located in a vertical direction is provided, a motion artifact according to the horizontal movement of a human body (namely, right and left movement) (a horizontal vector) is reduced.
A sleeve portion 410 of the clothing may be formed with a mesh structure having a net pattern, a slit structure having a narrow and long groove, a cut-out structure formed by greatly cutting out a partial portion, a folding structure having a pleat or a pleat structure. If a wearer of the clothing moves the arm, the body sheet of the clothing moves according to the movement of the arm. At this time, if the sleeve portion 410 has a mesh structure, a slit structure or a cut-out structure so that a hole is formed through the sleeve portion 410 which connects the shoulder and the arm of the clothing, even though the arm is moved, only the sleeve portion 410 is shrunken or expand so that the body sheet of the clothing does not move, thereby reducing a motion artifact according to the movement of the arm.
In the same principle, if the sleeve portion 410 has a folding structure or a pleat structure so that a pleat (not shown) is formed at the sleeve portion 410, as the pleat is folded or unfolded according to the movement of the arm, a motion artifact according to the movement of the arm is reduced.
A neck girth 420 of the clothing may have a mesh pattern, or a pleat may be formed at the neck girth 420. If a wearer of the clothing moves the neck, the body sheet of the clothing moves according to a movement of the cervical spine. At this time, as described above with reference to FIG. 2 h, the neckline 420 has a mesh pattern or a pleat (not shown), thereby reducing a motion artifact according to the movement of the cervical spine.
FIG. 3 a shows an example of a textile electrode kit according to an embodiment of the present disclosure, and FIG. 3 b is a diagram for illustrating an example of clothing to which the textile electrode kit of FIG. 3 a is applied.
The textile electrode kit 10 may be composed of only the electrode 110, composed of the electrode 110 and the three-dimensional structure 140, or composed of the electrode 110, the three-dimensional structure 140 and the signal detection module 130.
If the textile electrode kit 10 is composed of only the electrode 110, the electrode 110 is attached to the clothing electrode mounting portion 185 or coupled thereto by means of sewing 190. If the electrode 110 is a contact-type electrode, the electrode 110 is mounted to an inner side of the clothing electrode mounting portion 185, which is a portion coming into contact with the skin (by attachment or the sewing 190). If the electrode 110 is a non-contact electrode, the electrode 110 may be mounted to an inner or outer side of the clothing electrode mounting portion 185.
Here, the clothing electrode mounting portion 185 is a portion formed at the clothing with non-elastic material for the mounting of an electrode and may be the front center band 211, the back center band 231, the front abdominal band 241, the back abdominal band (not shown) or the like, or a pocket or tunnel formed thereat.
In FIGS. 3 a and 3 b, even though the textile electrode kit is depicted as having a circular shape for convenience, the present disclosure is not limited thereto, and the textile electrode kit may have various shapes.
If the electrode 110 is a non-contact electrode, the non-contact electrode is formed by mounting a spiral coil 115 on a coil-mounted textile sheet 175. The coil-mounted textile sheet 175 may employ the clothing electrode mounting portion 185, or the textile electrode kit 10 having a non-contact electrode may be mounted to the clothing electrode mounting portion 185. At this time, the electrode 110 receives an oscillation signal from an oscillation circuit and outputs a bio signal.
FIG. 4 a is a diagram for illustrating a textile electrode kit having a three-dimensional structure below a non-contact electrode according to an embodiment of the present disclosure, and FIG. 4 b is a diagram for illustrating a textile electrode kit having a three-dimensional structure below a non-contact electrode according to another embodiment of the present disclosure.
FIGS. 4 a and 4 b depict a three-dimensional structure 140 having a non-contact electrode formed by mounting the spiral coil 115 on the coil-mounted textile sheet 175, which is provided below the electrode 110, and the clothing electrode mounting portion 185 (or, the lower fixed member) is located below the three-dimensional structure 140.
In FIG. 4 a, a rim of the coil-mounted textile sheet 175 is coupled to the clothing electrode mounting portion 185 (or, the lower fixed member). In other words, the rim of the coil-mounted textile sheet 175 is sewed or attached to the clothing electrode mounting portion 185 (or, the lower fixed member).
In FIG. 4 b, an upper cover member 170 is further provided, and the rim of the upper cover member 170 is coupled to the clothing electrode mounting portion 185 (or, the lower fixed member). In other words, the rim of the upper cover ember 170 is sewed or attached to the clothing electrode mounting portion 185 (or, the lower fixed member).
The three-dimensional structure 140 has an electrode stabilizing foam (a buffering member) and is stably mounted to a human body while being less influenced by a movement of the human body even though the human body has bent portions, in order to reduce a motion artifact at the electrode 110 and buffer an external pressure. The three-dimensional structure 140 may employ any three-dimensional structure such as memory foam, sponge, Styrofoam, fabric or the like.
A single three-dimensional structure 140 is a single continuous material, which receives a movement of a human body at a bottom surface of the three-dimensional structure 140 and a portion in contact with the skin and transfers the movement to the electrode 110 through the upper surface of the single three-dimensional structure 140. Therefore, if the size of the cushion member 140 is reduced and the cushion members 140 are spaced to form a discontinuous space 147 between the cushion members 140, a motion artifact is not transferred in the discontinuous space 147, and as a result, the motion artifact transferred to the electrode 110 is reduced as much as the reduced area of the cushion member 140 and the increased area of the discontinuous space 147.
The lower fixed member (not shown) is located below the three-dimensional structure 140 to cover the lower portion of the textile electrode kit 10 and may be made of various materials such as fabric, rubber, vinyl, film, plastic or the like. At this time, the fabric may include a clothing fabric. If the lower fixed member is provided, the electrode 110 is not directly mounted to the clothing electrode mounting portion 185, and the textile electrode kit 10 may be freely used individually.
The upper cover member 170 is located above the spiral coil 115 to surround and cover the electrode 110 and may be made of various materials such as fabric, rubber, vinyl, film, plastic or the like.
FIG. 5 a is a diagram for illustrating a textile electrode kit having a three-dimensional structure above a non-contact electrode according to an embodiment of the present disclosure, and FIG. 5 b is a diagram for illustrating a textile electrode kit having a three-dimensional structure above a non-contact electrode according to another embodiment of the present disclosure.
In FIGS. 5 a and 5 b, an electrode 110 is provided, a three-dimensional structure 140 is located thereon, a signal detection module 130 is located thereon, and an upper cover member 170 is provided thereon. Here, the electrode 110 is a non-contact electrode, which is formed by mounting the spiral coil 115 on the coil-mounted textile sheet 175.
In FIG. 5 a, the coil-mounted textile sheet 175 and the upper cover member 170 are coupled. In other words, a rim of the coil-mounted textile sheet 175 is sewed or attached to the upper cover member 170. In this case, the electrode 110 is not directly mounted to the clothing electrode mounting portion 185, and the textile electrode kit 10 may be freely used individually.
In FIG. 5 b, the upper cover member 170 is coupled to the clothing electrode mounting portion 185 (or, the lower fixed member). Here, a rim of the upper cover member 170 is sewed or attached to the clothing electrode mounting portion 185 (or, the lower fixed member), which means that the upper cover member 170 is directly mounted to the clothing.
The signal detection module 130 drives the electrode 110 to detect a bio signal and is mounted in a housing. In case of a non-contact electrode, the signal detection module 130 includes an electrode driving unit 139 and a signal pre-processing unit 133.
The electrode driving unit 139 has an oscillation circuit composed of L and C and transmits an oscillation signal to a coil which is a non-contact electrode.
The signal pre-processing unit 133 demodulates the oscillation signal received from the coil which is a non-contact electrode to detect a bio amplifies the bio signal, and removes artifact.
If the electrode 110 is a non-contact electrode, namely having a coil-type magnetic induction sensor which forms a spiral coil on a textile sheet as shown in FIG. 5 a, the textile electrode kit 10 may be formed by sewing an outer portion (a circumferential portion) of the textile sheet of the electrode 110 and an outer portion of the upper cover member 170 together in a state of including the three-dimensional structure 140 and the signal detection module 130 therein. The prepared textile electrode kit 10 may be installed at an electrode-mounting tunnel or pocket located at a predetermined position of the clothing.
In addition, as shown in FIG. 5 b, the clothing electrode mounting portion 185 (or, the lower fixed member) may be sewed to the outer portion of the upper cover member 170 to fix and mount the textile electrode kit 10 at a predetermined position of the clothing.
In the present disclosure, a wire may be used to connect the electrode 110 to the signal detection module 130 so as to transmit a signal. On occasions, a snap button may also be used.
FIG. 6 is a diagram for illustrating a textile electrode kit having a three-dimensional structure above a contact-type electrode according to an embodiment of the present disclosure.
In FIG. 6, the electrode 110, which is a contact-type electrode, is mounted to a portion of the clothing electrode mounting portion 185 which comes into contact with the skin, a three-dimensional structure 140 is located on the clothing electrode mounting portion 185, a signal detection module 130 is located thereon, and an upper cover member 170 is provided thereon. The upper cover member 170 and the clothing electrode mounting portion 185 are sewed or attached.
The signal detection module 130 drives the electrode 110 to detect a bio signal and is mounted in a housing. In case of a contact-type electrode, the signal detection module 130 includes a signal pre-processing unit 133 for amplifying a signal and removing artifact.
In the present disclosure, the electrode 110 is used for detecting a bio signal and may be either a contact-type electrode for detecting a bio signal in direct contact with the skin or a non-contact electrode for detecting a bio signal by using a coil-type magnetic induction sensor without direct contact with the skin.
If the electrode 110 is mounted to a portion of the clothing electrode mounting portion 185 which comes into contact with the skin, the electrode 110 may be sewed, adhered or mounted by means of a coupling member such as a snap button, depending on the material of the electrode.
As shown in FIG. 3 b, regardless of whether the electrode 110 is a non-contact electrode or a contact-type electrode, a portion of the clothing electrode mounting portion 185 where the textile electrode kit 10 is located is made of an non-elastic material. Other portions of the clothing may be made of elastic material. The non-elastic material may be selected from various materials such as cotton and hemp, and the elastic material may be selected from various materials such as polyester, polyurethane, a mixture of polyester and polyurethane or the like.
Even though the lower fixed member and the upper cover member are illustrated as textile in the present disclosure for convenience, the present disclosure is not limited thereto, and in the present disclosure, the lower fixed member and the upper cover member may be made of various flexible materials such as film and vinyl.
FIG. 7 a is a diagram for illustrating a role of a three-dimensional structure, in case of a textile electrode kit having the three-dimensional structure above the electrode, in the present disclosure, and FIG. 7 b is a diagram for illustrating a role of a three-dimensional structure, in case of a textile electrode kit having the three-dimensional structure below the electrode, in the present disclosure.
In FIG. 7 a, similar to FIGS. 5 a, 5 b and 6, if the electrode 110 is located at a bent portion of a human body, artifact of a motion artifact or the like increases during a movement of a subject person, and thus a signal may not be normally detected. To solve this problem, in the present disclosure, the three-dimensional structure 140 is interposed between the electrode 110 and the housed signal detection module 130 so that the electrode 110 may be fit to a human body without moving, and thus it is possible to stably detect a signal while reducing a motion artifact during a movement of the subject person.
In FIG. 7 b, similar to FIGS. 4 a and 4 b, if the electrode 110 is located at a bent portion of a human body, artifact of a motion artifact or the like increases even by a little movement of a subject person, and thus a signal may not be normally detected. Therefore, in FIG. 7 b, the cushion member 140 is interposed between the electrode 110 and the human body so that the electrode 110, which is a non-contact electrode, may be spaced apart from the human body and less influenced by the movement of the human body. In particular, if the size of the cushion member 140 is reduced and the cushion members 140 are spaced to form a discontinuous space 147 between the cushion members 140, a motion artifact is not transferred in the discontinuous space 147, and as a result, the motion artifact transferred to the electrode 110 is reduced as much as the reduced area of the cushion member 140 and the increased area of the discontinuous space 147. By doing so, it is possible to stably detect a signal while reducing a motion artifact (a motion artifact) during a movement of the subject person.
FIG. 8 is a block diagram for illustrating a configuration of a signal detection module in case of having a non-contact electrode, and FIG. 9 is a block diagram for illustrating a configuration of the signal detection module having a contact-type electrode.
As in FIG. 8, in case of a non-contact electrode (namely, an inductor-type bio signal measurement sensor), the signal detection module 130 includes an electrode driving unit 139, a signal pre-processing unit 133 and a transmitting unit 137.
The electrode driving unit 139 includes an oscillation circuit composed of L and C and transmits an oscillation signal to the non-contact electrode 113. If so, a magnetic field is formed by a minute current flowing on the coil of the non-contact electrode 113. The magnetic field varying according to time induces an eddy current in the detection target (in the human body), and the induced current generates a minute magnetic field in a direction opposite to the magnetic field generated at the coil of the non-contact electrode 113.
The signal pre-processing unit 133 includes a demodulating unit (not shown), an amplifier (not shown) and a filter (not shown), demodulates an oscillation signal received from the non-contact electrode 113 to detect a bio signal, amplifies the bio signal, and removes artifact.
The transmitting unit 137 transmits the bio signal detected by the signal pre-processing unit 133. The transmitting unit 137 may employ wireless transmitting unit or a wireless transmission port for transmitting signals in a wired manner. In case of the wireless transmission port, a snap button or a connector may be employed.
As shown in FIG. 9, the signal detection module 130 which is a contact-type electrode 117 includes a signal pre-processing unit 133 and a transmitting unit 137.
The signal pre-processing unit 133 includes an amplifier (not shown) and a filter (not shown) to amplifiers the bio signal received from the contact-type electrode 117 and remove artifact.
The transmitting unit 137 transmits the bio signal detected by the signal pre-processing unit 133, and the transmitting unit 137 may be a wireless transmitting unit or a wireless transmission port for transmitting signals in a wired manner.

As shown in FIG. 10, an electrode-mounting tunnel (or, an electrode-mounting pocket) for mounting the textile electrode kit 10 to the clothing is formed by sewing two textile sheets. Here, the lower textile sheet may be made of non-elastic material, and the upper textile sheet may be elastic material. The electrode-mounting tunnel is formed by sewing right and left portions of the electrode-mounting tunnel as shown in FIG. 10, and thus two entrances are formed at the upper and lower portions.
The electrode-mounting pocket is formed by sewing right and left portions of the electrode-mounting tunnel and then further sewing one of upper and lower sides so that an entrance is formed at the other of the upper and lower sides. Here, the term “upper”, “lower”. “right” and “left” represents a direction indicated by four terminals in the cross shape, without being limited to upper, lower, right and left parts of the clothing.
As shown in FIG. 11, the textile electrode kit 10 is inserted by pressure into the entrance of the electrode-mounting tunnel.
Even though FIGS. 10 and 11 depict a straight tunnel structure, the present disclosure is not limited thereto but may have various tunnel structures such as a cross shape, a straight shape, a T shape, an inversed T shape, an O shape, a rectangular shape, a diamond shape, a triangular shape, a V shape, a “=” shape, a “≡” shape, a “

At this time, the C-shaped non-elastic unit and the inversed C-shaped non-elastic unit are symmetrically disposed based on the vertical axis so that their curved portions come into contact with each other. In other words, as a whole, the C-shaped non-elastic unit and the inversed C-shaped non-elastic unit are disposed at the front sheet with a shape similar to “X”. In addition, a band-type elastic member made of high-elastic or elastic material with a band shape may be disposed at the front sheet. At this time, the C-shaped non-elastic unit and the inversed C-shaped non-elastic unit are disposed across the band-type elastic member. However, the C-shaped non-elastic unit and the inversed C-shaped non-elastic unit may not overlap with the band-type elastic member, and a plurality of band-type elastic members may be placed on a straight line in contact with the C-shaped non-elastic unit and the inversed C-shaped non-elastic unit.
