光纤传感器检测呼吸压

TEST BREATH PRESSURE WITH FIBER SENSOR

本文介绍一种光纤呼吸传感器，用于呼吸压检测，其灵敏度比扩散硅式半导体压力传感器高，低频性能比压电式传感器好。

A fiber breath sensor for testing breath pressure is introduced in this paper.Its sensitivity is higher than which of the semiconductor and its property in low frequency is superior than that of the pressureelectric sensor.The results of practical tests are satisfied.
