The topic of energy harvesting is very important because of the rising power
consumption and environmental concerns. Extensive research is being done on Poly
(Vinylidene Fluoride) PVDF and its copolymers for the purpose of developing energy
harvesting devices. This chapter deals with the various types of piezoelectric devices
and their working principle, along with their applications. The use of PVDF and its
nanocomposites in piezoelectric devices makes them promising due to their
outstanding properties, such as ease of processing, good flexibility, good
biocompatibility, high stability, etc. Also, the applications of PVDF-based piezoelectric
materials in energy harvesting devices such as sensors, biomedical science, flexible and
hybrid nanogenerators, etc., are discussed.
