Abstract
Piezoelectric and acoustic properties of piezoelectric flexible composites or Piezo-Rubbers which have been developed at NTK-NGK are reported. The frequency dependences and hydrostatic pressure dependences of underwater receiving sensitivities of hydrophone using the Piezo-Rubber are discussed in terms of the properties of Piezo-Rubber materials. Also single pulse acoustic transmitting/receiving responses of the Piezo-Rubber are compared with those of PZT ceramics, PVDF polymer and PZT/polymer 1-3 type composites.Keywords
