Abstract

A smart monitoring system based on fiber-optic interferometers using multi-core fiber (MCF) is presented in this paper. Interference among cores in the seven-core fiber (SCF) was introduced by using multi-mode fiber (MMF) coupling and experimental setup was designed to collect the data of user on bed for processing. With optimized algorithm, three body activities, including on the bed, off the bed and body movement, can be identified successfully. For further processing on collected data, respiration of the user can also be obtained. The smart monitor is contactless and non-invasive which is user-friendly and secure.
