Energy harvesting devices are capable of harnessing waste ambient energy and are popularly known as green and renewable energy sources. Such devices can be used to empower electronic gadgets either by recharging the battery or by directly powering the electronic circuitry. This paper presents modeling and simulation of a piezoelectric vibration energy harvester based on a micro cantilever beam structure. The model is simulated in COMSOL Multiphysics® and a resonant frequency of 720 Hz is obtained. This energy harvester can be used to harness vibrational energy from vehicles and industrial machineries. Most importantly, the device generates a maximum power of 107 nW which can be used to operate quartz oscillators and wireless sensor and microcontrollers at standby mode.
