Analysis of Piezoelectric Energy Harvesters with Varying Width Profiles
Conventional piezoelectric-based vibration energy harvesters utilize a cantilever beam with uniform width, which has the disadvantage of decreased efficiency due to stress distribution on the beam surface. This project focuses on investigating the energy harvesting performances of cantilever beams with tapered widths. Beams with different geometries will be fabricated and the stress distribution at different frequencies will be determined by using a number of strain gages. The experiments will be performed on the electrodynamic shaker. NI DAQ equipment will be used.
- Fabrication of tapered beams and placement of strain gages.
