PZT/PVDF composite for actuator/sensor application

Currently, smart structures utilize both polymeric sensor and PZT-based actuators. The benefit of self-sensing calls for the development of integrated actuator/sensor composites. This paper addresses the development of this new class of smart materials;. Porous PZT ceramics were fabricated by several techniques. PVDF was subsequently infiltrated within the controlled porosity PZT. In addition, PVDF or its blends and PZT powders were in-situ processed to generate controlled piezo and mechanical property composites. Both actuating and sensing of this new class of composite materials were studied. The paper presents the processes-structure-property relationship of this new class of piezocomposites.
