介绍了一种基于PVDF压电薄膜材料研制而成的脉搏传感器。该脉搏传感器从手腕处获取微弱的脉搏信号,前端采用鼓式振动结构,最大的获取信号,提高灵敏度;后经电荷放大、滤波等信号处理电路从而实现了脉搏模拟信号和脉冲方波信号的输出。

This paper introduces a design of pulse sensor based on PVDF.This sensor can take the pulse signal from hand.It uses novel structure which is like a drum to get full signal and improve sensitivity in the front end of this sensor.In the next circuit section,pulse signal will be amplified and filtered,and then the real analog pulse signal and square wave can be gained to output for general use.
