Abstract

Piezoelectric polymers and ceramics are widely studied for their promising applications in actuators and sensor technologies. Polyvinylidene Fluoride (PVDF) is a piezoelectric polymer which is extensively studied due its piezoelectric response, chemical and mechanical durability. However, the inherent drawback associated with functional polymers is a poor electromechanical coupling. Though piezoelectric ceramics possess high electromechanical coupling they are brittle and not suitable for certain applications. Hence, organic-inorganic functional composites are believed to overcome both drawback of weak coupling in polymer and high brittleness of ceramics. There have been extensive studies on PVDF-lead based piezo composites, however, a lead free inorganic piezoelectric is preferred due to the environmental friendly requirements.
