A Study on Electromagnetic Harvester with Sputter Coated Cantilever Beam Using Finite Element Analysis

Abstract

The work is focussed on measuring model parameters of a piezoelectric bending energy harvester cantilever beam with sputter coated technique using finite element analysis. The beam was studied for a wide range of frequencies of about 100-1200Hz. The finite element simulation results confirm that the vibrations in the above mentioned frequency range can be effectively utilised to generate energy. Design of electrometrical vibration energy harvester was carried out with literature survey and the effect was analysed for the given length of beam to the voltage produced by the harvester. The Electromagnetic analysis induced voltage is validated with the help of commercial finite element software ANSYS. The simulation results revealed that the effect of sputter coating on the beam will increase the power generation.
