Abstract :
A wind energy harvest system by using piezoelectric polyvinylidene fluoride (PVDF) is proposed and investigated in this research. Nozzle accelerator is designed to collect wind from environment and increase wind velocity. Using the wind induced drag force to directly blow and vibrate the PVDF employed on the subsequent duct is a simple structure of generating electricity by means of piezoelectric direct effect. Battery-support pull-up circuitry is designed to harvest very small amount of electricity from PVDF.
