Abstract:
A shape detection device comprising:a first substrate, a first plurality of electrodes disposed in parallel and spaced in relationship to one another on said first substrate, a second substrate a second plurality of electrodes disposed in parallel and spaced relationship to one another on said second substrate, an adhesive securing said substrates together in parallel relationship to one another with said first and second plurality of electrodes disposed in parallel relationship to one another, said first and second substrates having edges and first and second plurality of electrodes having ends finished to lie in the same plane as said edges to define a shape discrimination surface for detecting shape and direction of movement of an object across said ends of said first and second plurality of electrodes, said adhesive being disposed within each of or between said first and second pluralities of electrodes and said first and second plurality of electrodes are disposed on said first and second substrates to hold said electrodes rigid and isolated from one another and individually surrounded by said substrates and said adhesive to render said discrimination surface rigid for detecting an object on said discrimination surface.
