摘要
声表面波(SAW)传感器是一种无线无源传感器,在元源传感、适应恶劣环境等许多方面具有普通传感器不能实现的优点。阐述了声表面波器件的原理和结构特点,并对射频信号收发、信息处理等关键技术进行详细论述,综述了近些年国内外的相关研究现状,并进行了总结与展望。
Surface acoustic wave （ SAW ） sensor is a kind of wireless passive sensor, which has advantages of passive sensing and suitable for harsh environments that common sensors cannot realize. Structure characteristics and principle of SAW device are reviewed, and key technologies such as RF signal transceiver and signal processing are mainly focused on,as well as related research stutus in recent years home and abroad is reviewed and summary and prospect are carried out.
