Abstract

This work presented the experimental analysis which focused on the realization of active volume within a crystalline
phase of semi-crystalline PVDF samples on energy harvesting efficiency. The transformation of mechanical into electrical
energy was performed by PVDF connected directly in series to a standard interface circuit. This work investigated both
commercial and synthesized PVDF. The maximum power of 2.6 mW was measured across the matching load of 1 M at 70 Hz
exciting frequency from commercial PVDF of 28 mm thickness. A decrease in power was observed when the sample thickness
increased. Generated power of prepared- and commercial-PVDF, however, were almost the same for the thickness of about
50 mm with an active area of 4 cm²
.
