Abstract
Piezoelectric materials can be used to convert mechanical energy into electrical energy. In this study, we investigated the possibility of harvesting from mechanical vibration force using a high efficient piezoelectric material-polyvinylidene fluoride (PVDF). A piezoelectric energy harvesting system consists of rectifier, filter capacitor, resistance. The experiments were carried out with impacting force to PVDF film with the thickness of 1 . The output power was measured with change in the load resistance value from 100 to 2.2 . The highest power was obtained under optimization by selection of suitable resistive load and capacitance. A power of 0.3082 was generated at the external vibration force of 5 N (10 Hz) across a 1 optimal resistor. Also, the maximum power of 0.345 was generated at 22 and 1 . The developed system was expected at a solution to overcome the critical problem of making up small size energy harvester.
