Hydrostatic piezoelectric property of composite PbTiO/sub 3/-P(VDF/TeFE) for hydrophone applications

In order to improve hydrostatic piezoelectric sensitivity of flexible piezoelectric composites, Lead Titanate (PbTiO/sub 3/) piezoelectric ceramics is incorporated because of its greater piezoelectric anisotropy. The composites are prepared by embedding ceramic PbTiO/sub 3/ particles in a copolymer matrix poly(vinylidene fluoride/tetrafluoroethylene) (P(VDF/TeFE)). The preparation of these composites and their dielectric and hydrostatic piezoelectric properties are reported in this paper. Their hydrophone applications are discussed.
