Fiber Optic Sensor Applications for Vital Signs Monitoring: A Review

Reflective epoxy resin/chitosan/PAA composite-functionalized fiber-optic interferometric probe sensor for sensitive heavy metal ion detection

“…In addition, it enables flexible structure and variable functional surface combination. 12,13 Many optical fiber technologies have been addressed for heavy metal ion detection in recent years, including fiber modal interferometer, microfiber, long-period fiber grating (LPG), fluorescence, surface plasmon resonance (SPR), and fiber Bragg grating (FBG). [14][15][16][17] In general, devices such as microfiber and LPG require an evanescent field to be exposed to the surroundings, and it can be modified by graphene oxide, black phosphorus, etc., which can induce enhanced light-matter interaction and therefore improve the refractive index (RI) sensitivity.…”

Fiber-Optic Cardiorespiratory Monitoring and Triggering in Magnetic Resonance Imaging

“…Previously, the role of FOS's in monitoring of cardiorespiratory activity as well as other vital signs and, particularly, their suitability for patient monitoring, including their integration into smart textile, have been reported [12], [13], [14], [15], [16], [17], [18]. This review paper focuses on the recent advances in monitoring of patient's cardiorespiratory activity during MRI with the option of MRI synchronization.…”
