Abstract :
In order to improve hydrostatic piezoelectric sensitivity of flexible piezoelectric composites, Lead Titanate (PbTiO3) piezoelectric ceramics is incorporated because of its greater piezoelectric anisotropy. The composites are prepared by embedding ceramic PbTiO3 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
