ABSTRACT:
There is provided a force sensitive device comprising a first conductive layer, a second conductive layer resiliently deformable to come into contact with the first conductive layer, a certain level of voltage being applied across the first and second conductive layers, a plurality of spacing members intervening between the first conductive layer and the second conductive layer and formed of an insulating material, and a resilient top layer of an insulating material overlaid on the second conductive layer and operative to cause the second conductive layer to come into contact with the first conductive layer under a force acting on a surface portion thereof, wherein the contact portion varies in area depending upon a position of the surface portion where the force acts so that the force sensitive device produces the signal having a voltage level which varies depending upon the position where the force acts.
