Using porous piezoelectret film to fabricated piezoelectric sensor, then put it on wrist to collect pulse vibration signals, and with the corresponding circuit and display device, we fabricated a new type of piezoelectret pulse analyzer. Due to adopting piezoelectret film as the pulse transducer, the pulse analyzer has high sensitivity, low distortion and good repeatability. In the pulse analyzer, the piezoelectric membrane electrode in the form of plasticizing encapsulated is easy to introduce interference. The sensor encapsulate as piezoelectric microphone has the strong ability of antiinterference ability, and FET has the advantage of easyintegration, lower cost, and the waveform figure measured similar to typical ECG waveform has great medical reference value.
