1. A flexible, capacitive touch sensor, comprising:

  • a thin, flexible, transparent substrate having a first side and a second side;

    a first layer of resistive material on said first side, said first layer being thin, transparent, electrically continuous, flexible and covering on said first side a surface coincident with an active touch area for said touch sensor, said first layer being adapted to receive an electrical potential across said first layer within said active touch area and to transmit an electrical signal indicative of the X and Y position of a point at which an object contacts said active touch area.
