Fabric sensing device

A touch-sensitive textile device comprising:

• a first set of conductive threads oriented along a first direction;
• a second set of conductive threads interwoven with the first set of conductive threads and oriented along a second direction;
• and
• a sensing circuit operatively coupled to the first and second set of conductive threads, wherein the sensing circuit is configured to:
• apply a drive signal to the first set of conductive threads, and
• detect a variation in resistance between any one of the first set of conductive threads and any one of the second set of conductive threads.

A touch-sensitive textile device comprising:

• a first set of conductive threads disposed in a first textile layer;
• a second set of conductive threads disposed in a second textile layer;
• a spacer structure separating the first and second textile layers, the spacer structure configured to deflect in response to a touch on the first or second textile layer;
• and
• a sensing circuit operatively coupled to the first and second set of conductive threads, wherein the sensing circuit is configured to:
• apply a drive signal to the first set of conductive threads, and
• detect a variation in resistance between any one of the first set of conductive threads and any one of the second set of conductive threads.
