Abstract
Abstract: With the development of wireless technology and micro-electro-mechanical technology, electrochemical batteries as power sources have many flaws. On the contrary, piezoelectric vibration energy harvesters receive more attention because of their advantages of simple structure, no pollution and easily microminiaturizing. Beginning with the piezoelectric materials and their piezoelectricity, the piezoelectric vibration energy harvesters are reviewed based on the structure design and energy harvesting circuit design in this paper. Based on the directivity and band of the piezoelectric vibration energy harvesters, the improvements of the structure design are introduced in detail. Based on the energy harvesting efficiency of the piezoelectric vibration energy harvesters, the improvements of the energy harvesting circuit design are also introduced. Finally, the development perspective of the piezoelectric vibration energy harvesters is summarized. This paper will be helpful for the researchers who are engaged in the studying on the piezoelectric vibration energy harvesting.
