Abstract
A touch-sensitive textile device that is configured to detect the occurrence of a touch, the location of a touch, and/or the force of a touch on the touch-sensitive textile 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. The sensing circuit may also be configured to detect a touch or near touch based on a variation in an electrical measurement using the first or second set of conductive threads.
