Abstract
This project was developed to harvest vibration energy using a piezoelectric energy harvester. The availability of home appliance vibration energy is a promising solution to get clean energy resources to manipulate wasted energy. When the appliances’ vibration hits the piezoelectric energy harvester surface, pressure is applied to the piezoelectric transducers and converts mechanical energy into electrical energy. The piezoelectric energy harvester’s efficiency depends on the availability of the home appliances’ vibration energy; thus, using multiple piezoelectric transducers in series generates more power. The piezoelectric’ alternating current (AC) output is fed to a Cockroft-Walton voltage multiplier (CWVM) to convert into direct current (DC) and boost the output. Four piezoelectric transducers connected in series have successfully produced a voltage of up to 4.7 V. Its output voltage can be harnessed to power low-voltage electronic devices.
