A flexible, capacitive touch sensor, and a method of manufacturing a plurality of such touch sensors, are provided. The capacitive touch sensor comprises a thin, flexible, transparent, insulating substrate. A thin, flexible, transparent layer of resistive material is applied to one side of the substrate, and a thin, flexible, transparent, pressure-sensitive layer of adhesive material is applied to the substrate's other side. A releasable sheet may cover this adhesive layer. A plurality of thin, flexible electrodes, electrical leads and conductive areas are applied to the resistive layer. A thin, flexible, transparent layer of protective material protects the touch sensor's active touch area. Compounds may be added to this protective layer to enhance its conductivity and lubricity. A reel-to-reel process for manufacturing a plurality of such capacitive touch sensors also is described.
