     DETAILED DESCRIPTION 
     The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. 
     The following disclosure relates generally to antenna assemblies for watch bands, and, more particularly, to stretchable antenna elements embedded into watch bands. The watch band provides wireless communication via an antenna embedded within the watch band in a manner that protects the structural integrity and operation of the antenna. 
     A wearable device, such as a watch, can include a watch body and a watch band for securing the watch to the user. In many traditional watches, neither the watch body nor any other device interacts with the watch band. Instead, the watch body operates independently or does not interact with the watch band while communicating with any other external device. The operating components of the watch body can be protected within a rigid housing. However, it can be desirable to provide certain components outside the rigid housing to more effectively utilize the space within the housing. It can also be desirable to position certain components at locations that are more accessible or that can be more effectively utilized when positioned outside the housing. 
     In contrast to traditional watches, watch bands described herein can be provided with electronic components that can be operated for wireless communication with other devices. For example, an antenna and appropriate control circuitry can be provided in a watch band, rather than in a watch body, to communicate with other devices. The antenna can be embedded within a body of the watch band to protect the antenna from an external environment. The embedded antenna can be concealed to enhance the aesthetic appearance of the watch band. 
     Because watch bands stretch, bend, and flex to conform to a wrist of a user, any components contained therein are subjected to forces that can potentially damage such components. Attempts to reinforce these components with durable housings can reduce the ability of the watch band to be compliant and comfortably conform to the wrist of the user. 
     The watch bands described herein provide antenna assemblies that adaptably stretch, bend, and flex with the bodies of the watch bands. With the features described herein, the embedded antenna assemblies avoid damage from applied forces while also maintaining the compliance and comfort of the watch band while worn by a user. 
     These and other embodiments are discussed below with reference to  FIGS. 1-14 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
     According to some embodiments, for example as shown in  FIG. 1 , a watch  10  includes a watch body  100  that is worn on a wrist  2  with a watch band  110 . The watch body  100  can be portable and also attached to other body parts of the user or to other devices, structures, or objects. The watch band  110  can be flexible and encircle at least a portion of the wrist  2  of a user. By securing the watch body  100  to the person of the user, the watch band  110  provides security and convenience. In some embodiments, the watch body  100  includes a display  104  and a housing for containing components. 
       FIG. 2  illustrates a perspective view of the watch  10 , including the watch body  100  and a watch band  110 . As shown, the watch body  100  includes a housing  106  that supports the display  104 . The watch body  100  can be worn on a user&#39;s wrist and secured thereto by the watch band  110 . The watch band  110  can be a continuous structure or assembled as separate portions (e.g., straps) that join together and provide adjustable size configurations. For example, a clasp  120  or another mechanism (e.g., buckles, buttons, latches, locks, snaps, threads, and/or pins) can be provided to adjustably connect separate portions of the watch band  110 . The watch band  110  includes lugs  112  at opposing ends of the band that fit within respective recesses or channels  116  of the housing  106  and allow the watch band  110  to be removably attached to the housing  106 . The lugs  112  may be part of the watch band  110  or may be separable (and/or separate) from the watch band  110 . Generally, the lugs  112  may lock into the channels  116  and thereby maintain connection between the watch band  110  and the housing  106 . The user may release a locking mechanism (not shown) to permit the lugs  112  to slide or otherwise move out of the channels  116 . In some watches, the channels  116  may be formed in the watch band  110  and the lugs may be affixed or incorporated into the housing  106 . While lugs  112  and channels  116  are illustrated, it will be recognized that other attachment elements, such as locks, latches, snaps, clasps, threads, and/or pins can be included on the watch band  110  for securely attaching to the watch body  100 . 
     As further shown in  FIG. 2 , the watch band  110  can include a watch band body  114  that defines a longitudinal length of the watch band  110 . The watch band body  114  can be formed from a compliant base material that is configured to easily contour to a user&#39;s wrist, while retaining stiffness sufficient to maintain the position and orientation of the wearable device on the user&#39;s wrist. It can be desirable that the compliant material of the watch band body  114  provide capabilities of bending, flexing, and stretching to facilitate secure and comfortable fit on a user. Suitable compliant materials may include plastic, rubber, leather, nylon, canvas or other fibrous, organic, polymeric, or synthetic materials. 
     In some embodiments, the watch band body  114  can be formed from a base material such as a fluoroelastomeric polymer, having a Shore durometer selected for flexibility suitable for easily contouring to a user&#39;s wrists and selected for having sufficient stiffness to maintain support of the electronic device when attached to a user&#39;s wrist. For example, bands in certain embodiments may have a Shore A durometer ranging from 60 to 80 and/or a tensile strength greater than 12 MPa. In some embodiments, a fluoroelastomeric polymer (or other suitable polymer) can be doped or treated with one or more other materials. For example, the polymer can be doped with an agent configured to provide the polymer with a selected color, odor, taste, hardness, elasticity, stiffness, reflectivity, refractive pattern, texture and so on. The doping agent can confer other properties to the fluoroelastomeric polymer including, but not limited to, electrical conductivity and/or insulating properties, magnetic and/or diamagnetic properties, chemical resistance and/or reactivity properties, infrared and/or ultraviolet light absorption and/or reflectivity properties, visible light absorption and/or reflectivity properties, antimicrobial and/or antiviral properties, oleophobic and/or hydrophobic properties, thermal absorption properties, pest repellant properties, colorfast and/or anti-fade properties, deodorant properties, antistatic properties, medicinal properties, liquid exposure reactivity properties, low and/or high friction properties, hypoallergenic properties, and so on. 
     As further shown in  FIG. 2 , the watch band  110  can include an antenna  140  and/or a control unit  130  embedded within the watch band body  114 . The watch band body  114  can entirely surround the antenna  140  and/or the control unit  130  such that no portion of the antenna  140  and/or the control unit  130  is exposed to an external environment. The watch band  110  can include multiple antennae  140  and/or control units  130 . 
     The antenna  140  can be positioned such that, while the watch band  110  is worn by a user, the antenna  140  is positioned and oriented in a manner that facilitates communication with another device. For example, the antenna  140  can face outwardly away from the user. The user can facilitate communication with an external device  90  by bringing the antenna  140  into the proximity of the external device  90  and directing the antenna  140  toward the external device  90 . 
     The antenna  140  and/or the control unit  130  can include or provide a radio-frequency identification (RFID) system that is configured to enable one-way or two-way radio-frequency (RF) communications with the external device  90 . The one- or two-way communication may include an identification of the watch  10  and/or the external device  90 . 
     The identification can be used to initiate a secured data connection between the two devices. The secured data connection may be used to authorize a transaction between the user and an entity that is associated with the external device  90 . 
     In some embodiments, the user may initiate a communication with the external device  90  by placing the watch  10  near an active region on the external device  90 . In some implementations, the external device  90  is configured to automatically detect the presence of the watch  10  and initiate an identification process or routine. The RFID system of the watch  10  can include a unique identifier or signature that may be used to authenticate the identity of the user. As previously mentioned, the identification process or routine may be used to establish a secure data connection between the watch  10  and the external device  90 . The secure data connection may be used to authorize a purchase or download of data to or from the watch  10 . In some cases, the secure data connection may be used to authorize the transfer of funds from a credit card or financial institution in exchange for a product that is associated with the external device  90 . Other transactions or forms of electronic commerce may also be performed using the wireless communication between the watch  10  and the external device  90 . 
     The antenna  140  can be used for other types of communication. For example, the antenna  140  can operate as a short-range wireless antenna (e.g., Bluetooth™ antenna), a near-field antenna, a Global Positioning System (GPS) antenna, and/or another antenna for a transceiver. 
       FIGS. 3 and 4  illustrate, respectively, a top view and a sectional view of a watch band  110 . As shown, the watch band  110  includes a lug  112  for securely attaching to the watch body. The watch band  110  further includes the watch band body  114  extending from the lug  112  along a longitudinal length (e.g., axis) of the watch band  110 . As described above, the watch band body  114  surrounds and/or houses the antenna  140  and/or the control unit  130 . 
     As shown in  FIGS. 3 and 4 , the control unit  130  is operatively connected to the antenna  140 . For example, one or more ends of the antenna can be directly connected to the control unit  130 . The control unit  130  can be positioned between the antenna  140  and the lug  112  to provide greater protection to the connection between the control unit  130  and the antenna. For example, in regions close to the lug  112 , the watch band body  114  may undergo less stretching and flexing than at other regions farther away from the lug  112 . 
     As shown in  FIG. 4 , the watch band body  114  has embedded therein the antenna  140  and/or the control unit  130 . The antenna  140  can include a first antenna layer  150  and a second antenna layer  170 . Each of the first antenna layer  150  and the second antenna layer  170  can form a coil that includes multiple windings about a central axis. The coil can be a spiral coil that lies within a plane, as described further herein. The planar configuration can provide a wide area for activity of the antenna without requiring a significant thickness within the watch band body  114 . 
     The antenna  140  can be formed from a material that provides desired mechanical and electrical properties. For example, the antenna  140  can include a mixture of an elastic polymer and conductive particles. The elastic polymer can include one or more of a variety of elastic materials, such as polyethylene terephthalate (pet) and polyimides. The conductive particles can include one or more of a variety of conductive materials, such as silver or carbon. It will be appreciated that a variety of mixtures can be provided to include both an elastic polymer and conductive particles. For example, the conductive particles can be any metal or combination of metals. The conductive particles can include silver, copper, gold, aluminum, zinc, nickel, brass, bronze, iron, platinum, steel, lead, stainless steel, and/or combinations thereof. The elastic polymer can include fluoroelastomers, perfluoroelastomers, polyether block amides, chlorosulfonated polyethylene, ethylene-vinyl acetate, thermoplastic elastomers, polysulfide rubber, elastolefin, polyisoprene, polybutadiene, chloroprene rubber, polychloroprene, neoprene, baypren, butyl rubber, styrene-butadiene rubber, nitrile rubber, ethylene propylene rubber, ethylene propylene diene rubber, epichlorohydrin rubber, polyacrylic rubber, silicone rubber, fluorosilicone rubber, and/or combinations thereof. The conductive particles can be provided in one of a variety of shapes, sizes, and distributions within the elastic polymer. The materials for the antenna  140  can be provided as an ink or paste that is applied to the watch band body  114  and cured, as further described herein. 
     The elastic polymer of the antenna  140  can provide desired mechanical properties, such as the ability to adaptably stretch, bend, and flex with the watch band body  114 . The antenna  140 , or at least a portion thereof, can be directly connected to (e.g., fixed to, adhered to, printed onto, cured onto, cross-linked to, and/or integral with) the watch band body  114 . For example, the watch band body  114  can surround and/or encapsulate an entirety of the antenna  140  within an interior region of the watch band body  114 . The watch band body  114  can provide an inner surface  118  that defines a boundary of the interior region, and the antenna  140  can be provided directly on the inner surface  118  of the watch band body  114 . In some examples, no intervening structure is provided between the antenna  140  and the watch band body  114 , such that the antenna  140 , or a portion thereof, is directly connected to the inner surface  118  of the watch band body  114 . Because the antenna  140  may desirably extend across a significant length of the watch band body  114 , at least some portion of the antenna  140  moves with the watch band body  114  while worn by a user. For example, the watch band body  114  may be stretched along a longitudinal length of the watch band  110 , and the first antenna layer  150  and the second antenna layer  170  can elastically stretch with the watch band body  114  without incurring damage (e.g., breaking, cracking, deformation). Similarly, the watch band body  114  may bend and/or flex about a wrist of the user, and the first antenna layer  150  and the second antenna layer  170  can elastically bend and/or flex with the watch band body  114 . 
     The conductive particles of the antenna  140  can provide desired electrical properties, such as conductivity along an entire length of the antenna  140 . The conductive particles can be provided in adequate amounts and/or density to provide the desired conductivity. The conductive particles can provide electrical conductivity while maintaining the stretchability and flexibility of the antenna  140 . 
     As shown in  FIG. 4 , the first antenna layer  150  and the second antenna layer  170  can be at least partially separated by an insulation layer  160 . For example, the insulation layer  160  can be positioned between portions of the first antenna layer  150  and portions of the second antenna layer  170 . The first antenna layer  150  and the second antenna layer  170  can be connected to each other through portions of the insulation layer  160 . For example, the first antenna layer  150  and the second antenna layer  170  can form a continuous loop from a first terminal of the control unit  130  to a second terminal of the control unit  130 . The control unit  130  can be directly connected to the first antenna layer  150  and operatively connected to the second antenna layer  170  via the first antenna layer  150 . 
     It will be appreciated that the antenna  140  can be provided with any number of layers. For example, the antenna  140  can include 1, 2, 3, 4, 5, 6, 7, 8, 9, or more than 9 layers. Any given pair of the layers can at least partially overlap or have no overlap. An insulation layer can be provided between any adjacent pair of layers with connections provided there through as desired. 
     Methods of assembling the watch band  110  are described herein. Exemplary stages are illustrated in  FIGS. 5-13  to produce the watch band described above. It will be appreciated that the described methods can be performed with variations in the order and number of operations illustrated. 
       FIGS. 5 and 6  illustrate, respectively, a top view and a sectional view of the watch band  110  in a first stage of assembly. As shown in  FIGS. 5 and 6 , the first antenna layer  150  is formed on the inner surface  118  of the watch band body  114  providing a base material (e.g., substrate). The first antenna layer  150  can be formed by printing on the watch band body  114  with a conductive ink (e.g., paste). The conductive ink can be allowed to cure with a thermosetting process that may include an elevated temperature and/or pressure for a duration of time. The resulting first antenna layer  150  can include multiple lengths that may or may not electrically connect to each other. For example, a second antenna layer may be required to complete a loop. As shown in  FIG. 5 , a first terminal end  152  and a second terminal end  158  can be provided to connect to a control unit (to be provided in a later stage). Each of the first terminal end  152  and the second terminal end  158  can be electrically connected to, respectively, a first connector end  154  and a second connector end  156 . The first connector end  154  and the second connector end  156  can be provided to connect to a second, overlapping antenna layer (to be provided in a later stage). 
       FIGS. 7 and 8  illustrate, respectively, a top view and a sectional view of the watch band  110  in a second stage of assembly. As shown in  FIGS. 7 and 8 , the insulation layer  160  is formed on the first antenna layer  150 . The insulation layer  160  can be formed by printing on the first antenna layer  150  with insulation ink. The insulation ink can be any ink that provides insulation, flexibility, stretchability, and adhesion. For example, the insulation ink can be a urethane-based and/or a silicone-based ink. The insulation ink can be allowed to cure with a thermosetting process that may include an elevated temperature and/or pressure for a duration of time. While the insulation layer  160  can be provided over significant portions of the first antenna layer  150 , the insulation layer  160  can leave exposed the first terminal end  152 , the second terminal end  158 , the first connector end  154 , and the second connector end  156 . The exposed portions allow for electrical connections to be made in later stages of assembly. 
       FIGS. 9 and 10  illustrate, respectively, a top view and a sectional view of the watch band  110  in a third stage of assembly. As shown in  FIGS. 9 and 10 , the second antenna layer  170  is formed on the insulation layer  160  and opposite the first antenna layer  150 . The second antenna layer  170  can be formed by printing on the insulation layer  160  with a conductive ink (e.g., paste). The conductive ink can be allowed to cure with a thermosetting process that may include an elevated temperature and/or pressure for a duration of time. As shown in  FIG. 9 , a third connector end  174  and a fourth connector end  176  can be provided to connect to the first antenna layer  150 . For example, the third connector end  174  and the fourth connector end  176  of the second antenna layer  170  can electrically connect to, respectively, the first connector end  154  and the second connector end  156  of the first antenna layer  150 . The electrical connections can be provided by printing directly through the openings in the insulation layer  160  to the first antenna layer  150 . As such, the first antenna layer  150  is operatively connected to the second antenna layer  170  through the insulation layer  160 . For example, the first antenna layer  150  and the second antenna layer  170  can form an electrically continuous pathway between the first terminal end  152  and the second terminal end  158  of the first antenna layer  150 . 
       FIGS. 11 and 12  illustrate, respectively, a top view and a sectional view of the watch band  110  in a fourth stage of assembly. As shown in  FIGS. 11 and 12 , a control unit  130  is connected to the first antenna layer  150 . In particular, the control unit  130  can be connected to the first terminal end  152  and the second terminal end  158  of the first antenna layer  150 . As such, the control unit  130  is directly connected to the first antenna layer  150  and operatively connected to the second antenna layer  170  via the first antenna layer  150 . The control unit  130  can be an integrated circuit or another type of circuit that controls operation of the antenna. 
       FIG. 13  illustrates another sectional view of the watch band  110  in the fourth stage of assembly. As shown in  FIG. 13 , a support member  180  is formed and connected to the control unit  130  and end portions of the first antenna layer  150 . The support member  180  can reinforce the connection between the first antenna layer  150  and the control unit  130 , which can be susceptible to breakage during assembly and/or while worn by a user. Forming the support member  180  can include an underfill potting operation. The support member  180  can be connected to the control unit  130 , the first terminal end  152 , and the second terminal end  158 . The support member  180  can be provided about part or an entire periphery of the control unit  130 . The support member  180  can be formed by application (e.g., as an adhesive paste). The adhesive paste can be allowed to cure with a thermosetting process that may include an elevated temperature and/or pressure for a duration of time. The adhesive paste can include an epoxy resin or other curable substance. When cured, the support member  180  has a rigidity that is greater than a rigidity of the watch band body  114 . 
     In a final stage of assembly, the first antenna layer  150 , the insulation layer  160 , the second antenna layer  170 , and the control unit  130  can be surrounded with additional portions of the watch band body  114  (e.g., base material). The final configuration can be as illustrated in  FIGS. 3 and 4 . The additional portions of the watch band body  114  (e.g., base material) can be provided in a molding process (e.g., in a second shot molding) to entirely surround and encapsulate the embedded components. The reinforcement provided by the support member can protect and maintain the connection between the control unit and the terminal ends of the antenna during the additional processing (e.g., molding). 
     A watch band can provide communication with an external device.  FIG. 14  illustrates a block system diagram of a watch  10 , including the watch band  110 . The watch band  110  can interact with an external device  90  via the antenna  140 . Interactions with an external device  90  can optionally be independent of the operations of a watch body. For example, the antenna  140  and the control unit  130  of the watch band  110  can form an RFID tag that communicates with the external device  90 . The external device  90  can include an antenna  92  and a processor  94  to act as a reader or interrogator for interactions with the watch band  110 . 
     To read the information encoded on the watch band  110 , transmitter-receiver of the external device  90  operates the antenna  92  to emit a signal to antenna  140 . The control unit  130  responds with the stored information via the antenna  140 . The information may include an identification of the watch band  110  or transmission of other information stored in the watch band  110 . When the external device  90  receives the transmission from the watch band  110 , the identification or other information can be used to select one or more corresponding actions to be performed by the external device  90 . For example, the identification or other information can be used to provide access to privileges or functions of the external device  90 . 
     The watch band  110  can be passive or powered. For example, the watch band  110  can use wireless energy from the external device  90  to perform its operations (e.g., to transmit its stored information back to the external device  90 ). Additionally or alternatively, the control unit  130  can include a power source that powers the transmission of information via the antenna  140 . 
     A watch band can provide various operations based on commands from a watch body.  FIG. 15  illustrates a perspective view of a connection mechanism of a watch, according to some embodiments of the present disclosure. An electrical connection can be made and maintained upon mechanical securement of the watch band  110  to the housing  106  of the watch body. The housing  106  of the watch body can include a watch body electrical connector  162 , for example, within a channel  114  formed in the housing  106 . The attachment member  112  of the watch band  110  can include a watch band electrical connector  164  for electrically connecting to the watch body electrical connector  162  when the attachment member  112  is connected to the housing  106 , for example by insertion into the channel  116 . For example, the watch body electrical connector  162  and/or the watch band electrical connector  164  can include pogo pins or other conductive surfaces for mutual contact and electrical connection. 
       FIG. 16  illustrates a block system diagram of a watch  10 , including the watch body  100  and the watch band  110 . The watch body  100  can include components for interacting with a user, the watch band  110 , and/or another device. The watch body  100  can include components that facilitate operation of the control unit  130  and/or the antenna  140 . 
     The watch band  110  can operate in concert with the watch body  100 . For example, the watch body  100  can control operation of the control unit  130  and/or the antenna  140 . The watch body  100  and the watch band  110  can include appropriate circuitry and connections to perform these operations. 
     As shown in  FIG. 16 , the watch body  100  can include components for interacting with a user. For example, the display  104  may provide an image or video output for the watch body  100 . The display  104  may also provide an input surface for one or more input devices such as a touch sensing device, force sensing device, temperature sensing device, and/or a fingerprint sensor. The display  104  may be any size suitable for inclusion at least partially within the housing of the watch body  100  and may be positioned substantially anywhere on the watch body  100 . The watch body  100  can further include one or more other user interfaces  166 , for receiving input from and/or providing output to a user. For example, one or more buttons, dials, crowns, switches, or other devices can be provided for receiving input from a user. The user interface  166  can include a speaker, a microphone, and/or a haptic device. A haptic device can be implemented as any suitable device configured to provide force feedback, vibratory feedback, tactile sensations, and the like. For example, in one embodiment, the haptic device may be implemented as a linear actuator configured to provide a punctuated haptic feedback, such as a tap or a knock. 
     As further shown in  FIG. 16 , the watch body  100  includes one or more processors  102  that include or are configured to access a memory having instructions stored thereon. The instructions or computer programs may be configured to perform one or more of the operations or functions described with respect to the watch  10 . The processors  102  can be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processors  102  may include one or more of: a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), or combinations of such devices. As described herein, the term “processor” is meant to encompass a single processor or processing unit, multiple processors, multiple processors, or other suitably configured computing element or elements. The memory can store electronic data that can be used by the watch body  100 . For example, a memory can store electrical data or content such as, for example, audio and video files, documents and applications, device settings and user preferences, timing and control signals or data for the various modules, data structures or databases, and so on. The memory can be configured as any type of memory. By way of example only, the memory can be implemented as random access memory, read-only memory, Flash memory, removable memory, or other types of storage elements, or combinations of such devices. 
     As further shown in  FIG. 16 , the watch body  100  may include a battery  168  that is used to store and provide power to the other components of the watch body  100 . The battery  168  may be a rechargeable power supply that is configured to provide power to the watch body  100  and/or the watch band  110  while being worn by the user. The watch body  100  may also be configured to recharge the battery  168  using a wireless charging system. 
     As further shown in  FIG. 16 , the watch body  100  may optionally include a watch body interface  162  that facilitates transmission of data and/or power to or from other electronic devices across standardized or proprietary protocols. For example, a watch body interface  162  can transmit electronic signals via a wireless and/or wired network connection. Examples of wireless and wired network connections include, but are not limited to, Wi-Fi, Bluetooth, infrared, RFID and Ethernet. The watch body interface  162  can communicate with or sense the watch band  110  via a watch band interface  164  of the watch band  110  when the watch band  110  is connected to the watch body  100  (e.g., with a lug of the watch band  110  inserted within a channel of the watch body  100  so the watch body interface  162  is in electrical contact with the watch band interface  164 ). The watch body  100  can provide power to the watch band  110  via the watch body interface  162  and the watch band interface  164 . 
     The control unit  130  can operate in concert with the antenna  140  to communicate with another device. The control unit  130  can perform operations based on commands generated by the processor  102  of the watch body  100  and communicated via the watch body interface  162  and the watch band interface  164 . The wireless operations of the antenna  140  can be via a wireless connection. Examples of wireless connections include, but are not limited to, cellular, Wi-Fi, Wi-Fi Direct, Bluetooth, short-range 802.11, near field communication (NFC), RFID, high frequency focused beams, WirelessHD, WiGig, and Wi-Fi IEEE 802.11ad. Accordingly, the watch body  100  can utilize the antenna  140  of the watch band  110  for communications with another device. Such connections can be used for phone calls, data transmission, messaging, and other types of communications facilitated by the watch body  100 . 
     A watch band can use its antenna to communicate with a watch body. As shown in  FIG. 17 , the watch body  100  can include an antenna  182  for communicating with the antenna  140  of the watch band  110 . The watch body  100  can further include a processor  102 , a display  104 , a user interface  166 , and/or a battery  168  to facilitate operation of the watch body  100 . The antenna  182  of the watch body  100  can be wirelessly connected to the antenna of the watch band  110  to communicate information from the watch band  110 . 
     To read the information encoded in the watch band  110 , a transmitter-receiver of the watch body  100  operates the antenna  182  to emit a signal to antenna  140 . The control unit  130  responds with the stored information via the antenna  140 . The information may include an identification of the watch band  110  or transmission of other information stored in the watch band  110 . When the watch body  100  receives the transmission from the watch band  110 , the identification or other information can be used to select one or more corresponding actions to be performed by the watch body  100 . For example, the identification or other information can be used to provide access to privileges or functions of the watch body  100 . Different functions can be performed by the watch body  100  based on the type of watch band  110  that is identified as being provided to the watch body  100  to form the watch  10 . 
     Actions performed by the watch body  100  in response to detection of a watch band  110  include influencing regular operation of the watch body  100 . For example, the regular operation of the watch body  100  can be maintained with additional or altered features based on the selected watch band  110 . As such, the user&#39;s experience with the watch body  100  during its regular operation is enhanced. 
     In some embodiments, upon identifying a particular watch band  110 , the watch body  100  provides a feature of a visual user interface that corresponds to a characteristic of the watch band  110 . For example, the watch body  100  can display on the display  104  a feature that is substantially the same color as the watch band  110 . Alternatively or additionally, the feature can be a similar color, a matching color, or a complementary color. Exemplary features include watch hands, text, numbers, symbols, graphics, charts, markers, or any displayed item. By further example, displayed information, watch faces, menu items, and selectable icons can be selected based on the selection of watch band  110 . 
     In some embodiments, upon identifying a particular watch band  110 , other settings of the watch body  100  can be modified. A watch band  110  can be associated with an activity that is supported by the watch body  100 . For example, an exercise band can be worn when a user is exercising. Upon identification of the exercise band, actions conducive to an exercise session can be performed by the watch body  100 . For example, the watch body  100  can display particular information, track activity of the user, take a biometric reading, record a location of the user, launch an activity tracking app, and/or modify notifications settings (e.g., to be more prominent). For example, the watch body  100  can display particular information, modify notifications settings (e.g., to be less prominent), provide reminders to the user, and/or record a location of the user. 
     The watch body  100  can perform a variety of other actions upon identification of a watch band  110 . It will be recognized that the detection of a watch band  110  can be followed by any associated action that can be performed by the watch body  100 . For example, where the watch body  100  has the required capabilities, the watch body  100  launches an app, opens a website, starts a timer, displays a message, provides an alert, communicates with another device, and/or other functions. 
     It will be recognized that one, some, or all of the components of the watch body  100  of  FIGS. 14-17  can be provided, alternatively or additionally, on and/or within the watch band  110  of the watch  10 . For example, a processor  102 , a display  104 , a battery  168 , a watch body interface  162 , and/or a user interface  166  can be provide on the watch body  100  and/or the watch band  110 . It will be further recognized that one, some, or all of the components of the watch band  110  of  FIGS. 14-17  can be provided, alternatively or additionally, on and/or within the watch body  100  of the watch  10 . For example, a control unit  130 , an antenna  140 , and/or a watch band interface  164  can be provide on the watch band  110  and/or the watch body  100 . 
     Accordingly, the watch bands described herein provide an antenna that can be operated for wireless communication with other devices. The antenna can be embedded within a body of the watch band to protect the antenna from an external environment and to conceal it from view. The antennas can adaptably stretch, bend, and flex with the watch bands body, thereby avoiding damage from applied forces while also maintaining the compliance and comfort of the watch band while worn by a user. 
     To illustrate the interchangeability of hardware and software, items such as the various illustrative blocks, modules, components, methods, operations, instructions, and algorithms have been described generally in terms of their functionality. Whether such functionality is implemented as hardware, software or a combination of hardware and software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application. 
     A reference to an element in the singular is not intended to mean one and only one unless specifically so stated, but rather one or more. For example, “a” module may refer to one or more modules. An element proceeded by “a,” “an,” “the,” or “said” does not, without further constraints, preclude the existence of additional same elements. 
     Headings and subheadings, if any, are used for convenience only and do not limit the invention. The word exemplary is used to mean serving as an example or illustration. To the extent that the term include, have, or the like is used, such term is intended to be inclusive in a manner similar to the term comprise as comprise is interpreted when employed as a transitional word in a claim. Relational terms such as first and second and the like may be used to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. 
     Phrases such as an aspect, the aspect, another aspect, some aspects, one or more aspects, an implementation, the implementation, another implementation, some implementations, one or more implementations, an embodiment, the embodiment, another embodiment, some embodiments, one or more embodiments, a configuration, the configuration, another configuration, some configurations, one or more configurations, the subject technology, the disclosure, the present disclosure, other variations thereof and alike are for convenience and do not imply that a disclosure relating to such phrase(s) is essential to the subject technology or that such disclosure applies to all configurations of the subject technology. A disclosure relating to such phrase(s) may apply to all configurations, or one or more configurations. A disclosure relating to such phrase(s) may provide one or more examples. A phrase such as an aspect or some aspects may refer to one or more aspects and vice versa, and this applies similarly to other foregoing phrases. 
     A phrase “at least one of” preceding a series of items, with the terms “and” or “or” to separate any of the items, modifies the list as a whole, rather than each member of the list. The phrase “at least one of” does not require selection of at least one item; rather, the phrase allows a meaning that includes at least one of any one of the items, and/or at least one of any combination of the items, and/or at least one of each of the items. By way of example, each of the phrases “at least one of A, B, and C” or “at least one of A, B, or C” refers to only A, only B, or only C; any combination of A, B, and C; and/or at least one of each of A, B, and C. 
     It is understood that the specific order or hierarchy of steps, operations, or processes disclosed is an illustration of exemplary approaches. Unless explicitly stated otherwise, it is understood that the specific order or hierarchy of steps, operations, or processes may be performed in different order. Some of the steps, operations, or processes may be performed simultaneously. The accompanying method claims, if any, present elements of the various steps, operations or processes in a sample order, and are not meant to be limited to the specific order or hierarchy presented. These may be performed in serial, linearly, in parallel or in different order. It should be understood that the described instructions, operations, and systems can generally be integrated together in a single software/hardware product or packaged into multiple software/hardware products. 
     In one aspect, a term coupled or the like may refer to being directly coupled. In another aspect, a term coupled or the like may refer to being indirectly coupled. 
     Terms such as top, bottom, front, rear, side, horizontal, vertical, and the like refer to an arbitrary frame of reference, rather than to the ordinary gravitational frame of reference. Thus, such a term may extend upwardly, downwardly, diagonally, or horizontally in a gravitational frame of reference. 
     The disclosure is provided to enable any person skilled in the art to practice the various aspects described herein. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. The disclosure provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the principles described herein may be applied to other aspects. 
     All structural and functional equivalents to the elements of the various aspects described throughout the disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for”. 
     The title, background, brief description of the drawings, abstract, and drawings are hereby incorporated into the disclosure and are provided as illustrative examples of the disclosure, not as restrictive descriptions. It is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. In addition, in the detailed description, it can be seen that the description provides illustrative examples and the various features are grouped together in various implementations for the purpose of streamlining the disclosure. The method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the claims reflect, inventive subject matter lies in less than all features of a single disclosed configuration or operation. The claims are hereby incorporated into the detailed description, with each claim standing on its own as a separately claimed subject matter. 
     The claims are not intended to be limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims and to encompass all legal equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirements of the applicable patent law, nor should they be interpreted in such a way.
