3、as been found many shortcomings that can not be ignored, such as big volume, heavy weight, limited power lifetime and regular replacement, and the material waste and environment pollution related to these problems. These shortcomings are more apparent, especially with the development of wireless net

4、work and embedded system. However, piezoelectric generator has no complex structure, no fever, no electromagnetic interference and no pollution, and it is easy to realize the miniaturization and integration. Besides, it can meet the power demand of low energy product. Thus, piezoelectric generator is becoming a hotpots research. This paper has adopted the way of combining theoretical analysis and experimental tests, and it has studied the fabrication proces
