Piezoelectric Vibration Energy Harvester Based on Thickness-Tapered Cantilever
Publié en 2015
The paper presents simulations of uniform thickness and thickness-tapered types of piezoelectric vibration energy harvesters using COMSOL Multiphysics software. The simulated vibration energy harvesters have bimorph cantilever structure with end mass. Tapering the thickness of the piezoelectric layer in bimorph towards the free end is found to improve the stress distribution in the beam and produce greater power.
