Design and Implementation Smart Respiratory Monitoring System Using Macrobend Fiber Sensor

Abstract

In this research, the researcher decided to use the technique of macro-curvature of optical fibers in the respiratory system activity monitoring system. A micro-serrated cell was made of Teflon, through which the optical fiber suffers multiple micro-curvature depending on the number of times inhaled and exhaled. A sensor sensitivity was obtained that reached 0.815 nm/number of breaths. The microcell was fixed on the back of the seat to be pressed by the tested case.
