Experiment Research on Power Generation Performance of Double Piezoelectric Vibration Energy Harvester

In order to collect the vibration energy in the environment, the cantilever double piezoelectric vibration energy harvester is designed to collect the mechanical vibration energy of the motor. The output voltage of the upper and lower piezoelectric ceramic wafer of the bimorph piezoelectric vibrator and the output voltage of the cantilever suspension length at different rotational speeds of the motor are investigated. At last the experimental results are verified. (paper)
