Abstract

A non-invasive vital signs monitoring system based on fiber-optic interferometers using single mode fiber (SMF) is presented in this paper. The fiber-optic interferometers was formed by a dual biconical structure without splicing point.The experimental setup was designed to collect the vital signs data of user on bed for processing. With optimized algorithm, human being’s heart beat and respiration signals can be monitored in an contactless and non-invasive way. The experimental results on the measurements of breathing rate and heart rate agree well with the results obtained from medical equipment.
