The simplofied realization method of pulse wave real-time detecting and parameters analysis system for daily health surveillance is described.Based on C8051 series MCU and integrated PVDF piezoelectric sensor

the radial artery pressure signals are collected.After filtering and smoothing the sampling data

the template function matching method adapted to pseudo-periodic signal is applied to estimate the pulse wave characteristic parameters online.As the filtering and the characteristic analysis for pulse signal processing both are carried out in time-domain

The pulse wave’s real time examination is fulfilled by using the simplest hardware.The experiment shows that the method of data processing is effective and the system is feasible.
