Devices related to a conductive fabric sensor are provided. A device can comprise an insulting and flexible fabric substrate, a central transmitting electrode on a top surface of the insulting and flexible fabric substrate, a plurality of receiving electrodes surrounding the central transmitting electrode and connected to the central transmitting electrode, and a power supply configured to generate a respective electric field between the central transmitting electrode and each receiving electrode of the plurality receiving electrodes.

A bracelet including two strands provided with a fastening system which includes at least one longitudinal groove on one of the two strands and at least one longitudinal protuberance on the other strand. The material and the shape of the groove and of the protuberance are configured such that these two elements interlock under pressure exerted by the bracelet user, over two overlapping portions of the bracelet strands. The connection between the strands can easily be separated, preferably by peeling the upper strand away from the lower strand. The bracelet is continuously adjustable in length, without requiring heavy or complex elements.

An accessory includes a band member and a button. The band member includes an elongated body defining a band interior cavity containing a fluid (gas or liquid) and further includes a band contact region formed along a length of the elongated body. The button has top and bottom portions and a body extending therebetween. The bottom portion is operably coupled to the band member. The body defines a button interior cavity that is in fluid communication with the band interior cavity, and further includes an expandable mechanism that includes first and second ends and a longitudinal axis. The expandable mechanism is movable between an expanded configuration and a collapsed configuration to selectively move the button between an expanded position and a collapsed position. Upon engaging the band contact region, the fluid urges the button to the expanded position.

A watch can include a watch body and a band for securing the watch to the user. The watch body can detect an identification of the band or combination of band portions, which can serve as an input to initiate actions performed by the watch body. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the watch body. Identification of the band can be performed by components of the watch body that also serve other purposes. The watch body can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the watch body.

A smart watch includes a watch strap and a flexible display panel. The first end of the flexible display panel is attached to the watch strap, and the second end of the flexible display panel is a free end. The flexible display panel has a bent state and a flattened state. When the flexible display panel is in the bent state, the flexible display panel and the watch strap are bent together and the flexible display panel is located on and in contact with an outer surface of the watch strap. When the flexible display panel is in the flattened state, the second end of the flexible display panel is out of contact with the outer surface of the watch strap and the flexible display panel is flattened in the same plane.

Attachment systems for attaching a wearable electronic device to a user including a sizing band and a retaining band are disclosed. The sizing band includes at least one sizing eyelet and a band-insertable end. The retaining band includes at least a post for insertion into the sizing eyelet of the sizing band and a concealment aperture configured to receive the band-insertable end of the sizing band. On a bottom surface of the retaining band can be a recessed guide bed configured to guide the band-insertable end along the bottom surface of the retaining band. A wearable electronic device can couple to both the sizing band and the retaining band by accepting an end portion of each band into receiving channels extending into opposite sidewalls of the housing.

Presented is an ergonomic wristband or a watchband for a wrist wearable device such as a smartwatch. The proposed wristband is structurally designed in a way to position the face of the wrist wearable device in a natural line of sight or convenient line of sight for a wearer. The proposed wristband when worn by the wearer would require no rotation or least rotation of the wearer's hand while viewing the face/display portion of the wrist wearable device mounted over the wristband.

A wearable device may include a watchcase defining a mounting slot and a key slot communicating with each other and a watchband. The watchband may include a strap-shaped body; and a clamping part connected to one end of the strap-shaped body and including a rotating part and a stop block arranged in the rotating part; the stop block is capable of moving out of or back into the rotating part; when the stop block moves into the rotating part, the clamping part is configured to be inserted into the mounting slot; after the clamping part is inserted into the mounting slot, the clamping part is configured to be rotated relative to the watchcase by rotating the watchband, and the stop block is configured to move out of the rotating part and is clamped in the key slot, such that the watchband is attached on the watchcase.

A watch strap assembly may include a first watch strap and a second watch strap. The first watch strap may include a first strap body and a confining strap. The confining strap may be integrally formed with the first strap body. The confining strap may be located between two opposite ends in a length direction of the first strap body. A channel is defined between the confining strap and the first strap body. The second watch strap may include a second strap body. An end of the second strap body may be capable of passing through the channel and being secured to the first strap body.

Watch band comprising lower and upper half band portions connected at a fold portion to surround a watch lug at the fold portion, each comprising a drilled hole for the passage of a double rivet comprising lower and upper bodies, either inserted one inside the other or each inserted into a common tube, the band including, at each double rivet, a snap means for ensuring a reversible axial stop for the lower body with respect to the upper body, comprising either a holding plate aligning lower and upper grooves of the lower and upper bodies, or two lower and upper clip lips of the common tube each clip fitted onto a complementary lower or upper lip of the lower or upper body.
