ZnO film based piezoelectric vibration energy harvester with two same sensing elements
A ZnO piezoelectric vibration energy harvester with two ZnO sensing elements in parallel connection is presented.The ZnO thin film is deposited by using RF magnetron sputtering method and the energy harvester is fabricated by using MEMS micromachining technique.The natural frequency of the fabricated ZnO energy harvester is 1300Hz.The tested results showed that this energy harvester has better output performance than that of the energy harvester with traditional design.The load voltage is 2.06V under load resistance of 1MΩ and the maximal load power is 1.25μW under load resistance of 0.6MΩ,when the prototype is excited by an external vibration with frequency of 1300Hz and acceleration of 10m/s2.
