Abstract

Abstract: Twenty healthy college students were selected as subjects. Four kinds of pulse wave sensors (adjustable， pencil probe， wrist-band， and photoelectric)were used to collect radial pulse waves. The influence factors， stability and reproducibility of the four sensors were studied. The results show that photoelectric sensor is susceptible to contact pressure， ambient light and measuring site， and it has medium reproducibility and poor stability; wrist-band pulse sensor is susceptible to measuring site， and its stability and reproducibility are medium; pencil probe sensor is susceptible to measuring site， and its stability and reproducibility are good; adjustable sensor is susceptible to pressure and measuring site， and it has good reproducibility and medium stability. Four kinds of pulse wave sensors have their own performance indexes and application scopes. The pencil probe sensor has less influence factors and better performance indexes.

Key words: pulse wave, sensor, performance, reproducibility, quantitative analysis
