Abstract
Abstract: Piezoelectric materials are gradually becoming attractive materials for research as far as energy harvesting technologies are concerned. The piezoelectric effect is a pressure-driven phenom-enon that is exhibited by various kinds of crystals, ceramics, polymers, and composites. However, polymers are preferred in piezoelectric applications owing to their flexibility and lightweight. They can easily be incorporated into electronic wearables that cover the demand for flexibility which is one of the most important requirements to improve technology. In this regard, the piezoelectric polymers are found as suitable candidates for energy harvesting. The present review provides a conclusive outlook of polymer-based piezoelectric materials in terms of doping of different fillers in different piezoelectric polymers with a special focus on polyvinylidene fluoride [PVDF] polymer to develop flexible energy harvesters. Moreover, the electrospinning process, a composite fabrication technique has been discussed to cover all the aspects of processing and optimization. Based on significant en-ergy storage capacity PVDF-based flexible electrospun web could be effectively used in day-to-day life.
