Ceramic Piezoelectric Transducers

Abstract

A major part of the effort has been concerned with the development of new techniques for the fabrication of diphasic ceramic and ceramic: plastic composites and with investigation of the manner in which local and macroscopic symmetry and phase interconnection (connectivity) controls the coupled elasto- electric (piezoelectric) and thermo-elasto-electric (pyroelectric) properties of the composite. Replicating a natural microstructure of desired connectivity, a new type of flexible ceramic elastometer composite has been developed which exhibits g sub 33 constants over an order of magnitude larger than PZT and has interesting potential for many passive voltage generation applications such as in hydrophones and towed arrays.
