  • Apple’s latest fabric related invention relates to touch-sensitive devices and, more specifically, a textile-based touch-sensitive device.

In some embodiments, the touch-sensitive textile device includes a first set of conductive threads oriented along a first direction, and a second set of conductive threads interwoven with the first set of conductive threads and oriented along a second direction.

The device may also include a sensing circuit that is operatively coupled to the first and second set of conductive threads. The sensing circuit may be configured to apply a drive signal to the first and second set of conductive threads to produce a charge on each of the first and second set of conductive threads. The sensing circuit may also be configured to detect a variation in charge or on any one of the first and second set of conductive threads.

In general, it may be advantageous to implement touch-sensitive functionality using a broad range of materials that can be integrated into a number of flexible and versatile form factors. In some implementations, a touch-sensitive textile may be incorporated into a consumer electronic product, including for example, a wearable electronic device. For examplethe touch-sensitive textile may be incorporated into a portion of the band or lanyard that is used to secure the device to the body of a user.
