Abstract: A fabric-based item may have fabric with conductive strands of material. The conductive strands of material may include conductive yarn formed from insulating fibers and conductive fibers. The conductive fibers may be metal wires. The insulating fibers in the conductive yarn may hide the conductive fibers from view. The fabric may be woven fabric or other fabric with intertwined strands of material. The woven fabric may include conductive and insulating warp yarns and conductive and insulating weft yarns. Conductive yarn may be coupled to capacitive touch sensor circuitry and may form a capacitive touch sensor grid or other capacitive touch sensor electrode structures. Conductive yarn may also be soldered or otherwise coupled to electrical components.

Abstract: A force sensor and force-sensing structure for use as input to an electronic device. A user touch event may be sensed on a display, enclosure, or other surface associated with an electronic device using a force sensor adapted to determine the magnitude of force of the touch event. The sensor output, corresponding to the magnitude of force, may be used as an input signal, input data, or other input information to the electronic device. A force sensor may include an array of upper electrodes disposed on a first substrate and a compliant medium disposed in a gap between the first substrate and a second substrate. At least one lower electrode may be disposed on the second substrate. The first substrate may be configured to deflect relative to the second substrate over a localized region when a force is applied to the force-receiving surface.
