| Abstract: | 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. |
