ABSTRACT:
A force sensor is provided which incorporates a piezoceramic element between first and second members that are moveable relative to each. The piezoceramic element is disposed within a cavity that is formed in the first member. The cavity extends between an opening and a wall within the first member. A second member is disposed within the cavity and slideably associated therewith. A spring is provided to permit the piezoceramic element to be preloaded without damaging it. First and second conductive elements are disposed on opposite sides of the piezoceramic element to facilitate electrical connection between the piezoceramic element and an external device.
