| Abstract: | On the base of analyzing the character of the pulse signal ot human body, a project for measuring the pulse signal was designed. The work principle of the PVDF piezoelectric-film sensor was presented, and the design of its signal processing circuit was also discussed. During the processing of pulse signal, the mean filtering used for eliminating the nosie of human body vibration was introduced in detail. The experiment indicated that this system had good sensitivity, and can accurately obtain the pulse signal. |
