US Patent 10061462 Touch sensor fabric

A method and apparatus are provided for a touch sensor made from a combination of conductive and non-conductive fibers. The fibers are woven into a fabric wherein non-conductive fibers keep horizontal conductive fibers from contacting vertical conducting fibers unless a touch is applied. The conductive fibers are grouped into horizontal and vertical strips and the fibers in a strip are connected together throughout the fabric. The ends of the strips are connected to control electronics that drive signals to the sensor fabric and measure signals from the sensor fabric to determine touch locations and touch contact areas.
