The issues involved with recording vital functions in the magnetic resonance imaging (MRI)
environment using fiber-optic sensors are considered in this paper. Basic physiological …

In this article, we briefly describe the design, construction, and functional verification of a
hybrid multichannel fiber-optic sensor system for basic vital sign monitoring. This sensor …

In this study, we investigated plastic optical fiber (POF) pressure sensors embedded in
mattresses to measure respiration and heart rate for sleep performance monitoring. The …

This paper reports on a textile fiber optic microbend sensor for heartbeat and respiration
monitoring. A section of multimode optical fiber sandwiched between parallel strips acting as …

Flexible sensors are the main components of wearable devices. Compared with flexible
substrate-based skin-like sensors, flexible textile sensors have the intrinsic advantages of …

Respiration rate (RR) is an important information related to human physiological health. A
wearable optical fiber sensor for respiration monitoring based on a bend singlemode …

We propose and demonstrate the feasibility of using a highly sensitive microbend multimode
fiber optic sensor for simultaneous measurement of breathing rate (BR) and heart rate (HR) …

This paper focuses on the design, realization, and verification of a novel
phonocardiographicbased fiber-optic sensor and adaptive signal processing system for …

A smart mattress based on optical fiber Mach-Zender interferometer (OF-MZI) is designed for
