基于压电原理的呼吸检测系统设计

Design of breath detection system based on piezoelectric principle

本文基于Arduino开发板,设计了基于压电原理的呼吸检测系统。系统采用柔性聚偏氟乙烯(Polyvinylidene Fluoride,PVDF)压电薄膜传感器采集呼吸信号,实现了无接触式检测到呼吸信号。该传感器不仅可以避免使用者在使用时的尴尬,也减少了使用者的看病时间和费用,同时还可以更加紧凑有效的使用医护资源。设计过程中将数据传入云端,为使用者及时查看提供方便。

In this paper,a breath detection system based on piezoelectric principle is designed based on Arduino development board.The breath signal is collected by Polyvinylidene Fluoride(PVDF)piezoelectric film sensor.The sensor can detect breath signal without contact.It can not only avoid the user’s embarrassment when using,but also reduce the user’s time and cost of seeing a doctor.At the same time,it can also use medical resources more compact and effectively.It is even more convenient for users to transfer data to the cloud for timely viewing during the design process.
