1. A touch sensor, comprising: an electrically insulating substrate having two sides and a touch region on one of the two sides; a plurality of electrically-conducting band segments coupled to and traversing the touch region and wherein the band segments are insulated from one another; a cover layer overlying the touch region; a controller providing an electrical means of sequentially energizing a plurality of the said segments and an electrical means for monitoring the electrical characteristics of the touch sensor and for identifying the location at which at least one touch position on the touch sensor is touched from the monitored electrical characteristics.
