Piezoelectric Vibration

The working principle of piezoelectric vibration energy harvester is described. A piezoelectric cantilever and mass composite structure is proposed to harvest vibration energy in resonance mode, and the mass is added on the edge of the cantilever to decrease the natural frequency of the whole structure. The finite element analysis was carried out on the composite structure using the ANSYS software. The displacement results were obtained by structural analysis, and the first order natural frequency was also obtained by modal analysis. Finally, the influence rules among the structural parameters, such as length and width of the cantilever, length and thickness of the mass and width of the PZT, and the natural frequency, piezoelectric output voltage are discussed in detail. Finally, the optimal structure of the harvester is obtained.

Simulation Results

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.
