Abstract
A variable resistance transducer responsive to an applied pressure including a smooth resistive layer on a flexible substrate and deposited thereon by printing or imaging technology, small points of nonconductive or semiconductive material, and resistive interdigitating fingers where in one finger is a wiper so that position on the resistive layer can be sensed.
