摘要
采用聚丙烯孔洞型铁电驻极体薄膜作为机电转换材料,将其层叠封装制成压力传感元件,并设计电荷放大器将其输出信号放大,用无线发射模块/无线信号接收模块连以信号处理模块,做成无线传感器。这种无线传感器可用于报警、运动监测。
One piece of piezoelectric-film of ferroelectret polypropylene is piled up to make a sensor by encapsulation.An amplifier is designed to enhance the output signal,then direct the amplified signal to a wireless transmitter,and a wireless receptor is contacted to a signal-processing module.This kind of wireless sensor can be used for alarming and activity monitoring.
