Vibration Powered Piezoelectric Generator Using Finite Element Method
Energy harvesting is a renewable and green power generation and is key technology of future having wide
application in wireless Sensors, NEMS, MEMS, UAV, medical implant devices, health monitoring and many more (1).
Approach used in this model is simple based on basic piezoelectric, beam theory. We applied this model to predict the power
generated from a bimorph cantilever beam with harmonic oscillations using PZT as a piezoelectric material to supply output
power to wireless sensor node. The model used to develop a genetic algorithm for optimization of an energy harvester
design. The existing designs meet all engineering constraints and can be utilized for other applications as well. These results
are validated to a certain degree with finite element analysis.
