Abstract: Micro piezoelectric vibration generator with high energy density may provide infinite and continuous energy for wireless sensor network. In order to improve generating capacity under given dimension, aiming at external force and displacement incentive environment, mathematics model of piezoelectric cantilever generator generating capacity are established, and influence law of unimorph and bimorph piezoelectric generator structural parameter on output voltage are analyzed by finite element simulation. The results show that on external force incentive environment, the output voltage increase linearly while length increase and decrease inverse proportion while width increase; on displacement incentive environment, the output voltage decrease while length increase and don't change while width vary; meanwhile, relation between thickness ratio and output voltage isn't affected by incentive environment, and bimorph piezoelectric generator with low thickness ratio should be selected at first for obtaining higher output voltage.

 

Keywords: Wireless sensor network, Vibration energy harvesting, Piezoelectric vibration generator, Microcantilever.
