Abstract
In order to harvest low-frequency vibration energy of environment
analyze characterstics of piezoelectric vibration energy harvesting technology
and set up math model. Simulation on property of energy harvester is carried out by numerical analysis software
prototype with four annular cantilevers is made. Theoretical and experimental models are presented. Based on state space equations
numerical analysis are performed. Opencircuit voltage and voltage output load resistance at different accelerations of low-frequency 0
500 Hz vibration sources are obtained by experiment and the experimental result is compared to theoretical result.
