Abstract
This study aimed at fabricating the PVDF-based piezoelectric energy harvester with high flexibility and efficiency. PVDF Nano-fiber was synthesized by using the electrospinning process. This study utilized the ink-jet printer to make the silver contact for the PVDF energy harvester. Later, the energy harvester was coated with Polydimethylsiloxane (PDMS) with different thickness. The result shown that the PVDF energy harvester tend to harvest the vibration at the frequency lower than 100 Hz. Moreover, the coating layer can decrease the energy harvesting efficiency due to its vibration absorption. This result was further validated by the Comsol Multiphysics simulation.
