摘要
为了测量脉搏信号,研究设计了压电陶瓷脉搏传感器及测量装置,该传感器利用压电陶瓷正压电效应制成,实测表明可得到信噪比高的脉搏信号。
In order to measure the pulse signal, the piezoelectric ceramic pulse sensor and measuring device are designed. The sensor is made of piezoelectric ceramic with positive piezoelectric effect. The actual measurement shows that the pulse signal with high signal-to-noise ratio can be obtained.
