A new piezoelectric vibration energy harvester was proposed to improve its output characteristics. The piezoelec-tric beam was arranged in array. Two magnets were introduced to improve the structure. The mathematics model of proposed ener-gy harvester was established;and based on dimensionless method, the output power and energy conversion efficiency of the sys-tem by inputting white noise were simulated by Matlab. The analysis shows that the output power and energy conversion efficiency of the proposed vibration energy harvester are improved efficiently.
