Performance Study of Piezoelectric Energy Harvesting to Flash A LED

Jedol Dayou, Man Sang Chow

Abstract


In this paper, analytical model of parallel and series configurations of identical piezoelectric benders with the increasing number is derived and studied to understand the performance of harvesting electric charge and power to flash a Light Emitting Diode (LED). Experiment was carried out where the flashing intervals of the LED were used to measure the harvesting performance. The benders in parallel configuration were found to perform the best as the number increases. The workability of the benders as a module of self-powered decorative LED as well as an autonomous sensor for monitoring shaking amplitude with reference to the flashing interval was then validated within the consideration of the structural damping.
