ELECTROSTRICTIVE DRIVING DEVICE, PROCESS FOR SONIC WAVE PROJECTION AND POLYMER MATERIALS FOR USE THEREIN

摘要

The provided invention is a novel electrostrictive driving device which comprises a sonic wave projector element having alternating electrodes and polymer material film layers. The device provides when subjected to a high bias voltage and a superimposed A.C. voltage, a high Angstroms/Volt response. Also, provided is a process for projecting sonic waves using the electrostrictive driving device of this invention.
