ABSTRACT:
An electromechanical transducer for the generation of an electric signal in response to a force or motion applied to the tactile surface thereof. The electromechanical transducer comprises a stack of planar sheets of a piezoelectric polymer material, each sheet having two opposed broad flat faces and at least one tactile surface at one longitudinal end, separate electrodes covering portions of each flat face of the sheets in predetermined patterns, terminals electrically connected to said electrodes for passage of said electric signal and means for detecting and amplifying the electric signal generated in response to a force or motion applied to the tactile surface of the transducer.
