微机电系统(MEMS)将是2l世纪最重要的研究领域之一,而微能源器件是MEMS其中一个重要分支,其发展直接关系到MEMS在某些领域中的应用。现针对压电式能源获取装置在国际上的研究进展进行系统的阐述和介绍,以压电效应的本质特征为基础,详细描述了它的结构、原理和应用领域。
MEMS will be one of the most important realm of science in 21th century,and micropower which is a branch of MEMS directly relates to development of MEMS in some applied realm. Aiming at the overseas progress on piezoelectric advice which can harvest power from vibration, based on piezoelectric effect the structure, principle and applied domain of piezoelectric energy harvesting advice are introduced.
