%X 摘要 选取20名健康大学生作为研究对象，分别使用4种不同脉搏波传感器(可调式、笔形探头式、腕带式、光感式)进行脉搏波数据采集，研究4种传感器的影响因素、稳定性、重复性的差异.结果表明，光感式传感器易受压力、环境光、测量部位的影响，重复性一般，稳定性差;腕带式传感器易受测量部位的影响，稳定性和重复性一般;笔形探头式传感器易受测量部位影响，稳定性和重复性好;可调式传感器易受压力、测量部位的影响，重复性好，稳定性一般.可见4种传感器有各自的性能指标与适用范围，其中笔形探头式传感器影响因素少，有较好的性能指标.</br>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.
