Abstract:With the growing demand and environmental concerns regarding applied electronic materials, a shift toward lead-free piezoelectric materials has been seen since the past decade. Polyvinylene difluoride (PVDF) serves as a lead-free and ultralight-weight piezoelectric polymer for flexible self-powered sensors and actuators; however, it suffers from low energy harvesting efficiency (10−12 V maximum output at a typical pressure in the range of 10−20 N/cm 2 for pure PVDF) due to the dominance of the nonpolar alpha (… Show more
