Abstract


The main subject of study, piezoresistive pressure sensor manufacturing human body pulse detector and pulse waveform clinically significant relations cases data acquisition and pulse processing analysis . This paper presents a set of sensor technology, analog electronics, digital electronics, microcontroller technology and computer technology in a pulse acquisition system . The article elaborated on the the pulse sensor design principle and its peripheral measurement circuit . Easy to produce zero drift for the hardware system , anti-interference ability and poor problem , the system uses the integrated chip - isolation amplifier AD202 as a signal amplification device . And the collected data transceiver ADM202 serial communication with the PC . The results of clinical trials of acquisition : The design of the system are high sensitivity, good reproducibility , high pulse shape recognition . Finally, the proposed rough set theory of the relationship between the pulse parameters and TCM Syndrome , a new algorithm for the study of the relationship between the two , new ways . The calculation results show that the measured pulse and dialectical conclusions have a certain relationship .
