摘要：随着微电子、无线网络和MEMS等低耗能产品的应用日益广泛，以化学电池为其主要供能方式存在着诸多弊端，而压电俘能器具有结构简单、不发热、无电磁干扰、无污染和易于实现机构的微小化、集成化等诸多优点，且能满足此类低耗能产品的供能需求而备受关注。综述了压电俘能技术的国内外研究现状。围绕提高压电俘能效率，从压电振子构成形式、能量存储电路和能量存储元件等方面进行了系统的介绍，并对压电俘能技术的发展方向进行了预测。压电俘能技术可应用于导弹引信，海啸预警、桥梁安全监测、石油输油管道监测等重要领域的安全检测装置的自供能系统中，同时也可为无线网络、嵌入式系统和MEMS等低耗能产品的实现无线供能，展现出了压电俘能技术的良好应用前景。

Abstract :With using micro-electronics、wireless sensors and MEMS more convenience, however electrochemical batteries as the power source have many flaws, piezoelectric harvestings have more attention because of the advantage of simple structure, less heat, less electromagnetism interfere, no pollution and easily microminiature, and the power generated can easily satisfied with the requirement of these productions. The piezoelectric energy harvesting is reviewed. The following articles have all investigated ways to improve the efficiency of power energy harvesting by altering the configuration of the piezoelectric device circuitry and power storage in order to maximize the energy extracted from the ambient source and the development of piezoelectric energy harvesting was studied. Piezoelectric energy harvesting as the power source can be used in missile fuze, bridge health scrutiny, ground sea forenotice system and so on. It will also brine fast increasing in system of micro wireless sensor, integrate with system and self-power MEMS.
