Recent developments of piezoelectric ceramic products and composites of synthetic rubber and piezoelectric ceramic particles

Abstract The theory on the dielectric and piezoelectric constants of the composites, with 0–3 connectivity, of synthetic rubber and piezoelectric ceramic particles is derived based on “modified'’cubes model. The dielectric and piezoelectric constants of the composites of chloroprene rubber and ceramic particles of PZT or PbTiO3 are reported. Also the applications of the composites and the piezoelectric ceramic products recently developed at our laboratory are explained.
