摘要
从周围环境中捕获能量是目前研究的热点。利用压电效应将振动、压力等机械能转化为电能是一种效率非常高的能量捕获方式。阐述了国内外压电式能量捕获装置的开发现状,指出未来压电式能量捕获装置必将朝着微型化、集成化、多样化的方向发展。
Energy harvest from surrounding has recently been focused on.Transformation of electric energy from machinery energy using piezoelectric effect is a high effective way of energy harvest.The development status of energy harvesting device is summarized at home and abroad.Finally,the directions in the future were pointed out to go along miniaturization,integration and diversity.
