Ferroelectric ceramic-polymer composites are considered as promising materials for applications in sensors, actua-tors and hydrophones. They are attractive for application as they exhibit high piezoelectric and pyroelectric res-ponse, low acoustic impedance matching with water and human skin and their properties can be tailored to various requirements. The advantage of composites over conventio-nal ceramics is that they have better mechanical shock resistance and more durable. The simplest ceramic-polymer composite is that which consists of ceramic particles dispersed in a polymer matrix (0-3 connectivity). The present investigation concentrates in the preparation and characterization of 65 PMN-35 PT-PVDF composites.
