Abstract

To deal with the low-frequency vibration energy in daily environment, the harvester's electromechanical coupling model was made based on the piezoelectric structure with double clamped trapezoidal beam piezoelectric structure, and corresponding experiments were conducted to verify the model. The research shows that the results of the theoretical model are in good agreement with the results of the experiments. When the trapezoidal beam structure is in a state of resonance (96.85 Hz) and the acceleration is 2 m/s2, open circuit output voltage is 44.43 V and the maximum output power is 6.16 mW. In addition, in order to compare double clamped trapezoidal structure and rectangular beam structure, experimental results shows that the double clamped trapezoidal beam piezoelectric structure has the function of reducing resonance frequency; compared with the rectangular structure, its output open circuit voltage increases by 22.7%, the output optimal load power increases by 33.0%.
