We propose and experimentally demonstrate a high-performance relative humidity (RH)
sensor by depositing graphene oxide (GO) onto tilted fiber grating (TFG). The largely tilted …

Vital signs not only reflect essential functions of the human body but also symptoms of a
more serious problem within the anatomy; they are well used for physical monitoring, caloric …

A low-cost wearable pulse and respiratory monitoring system based on D-shaped single
mode fiber (SMF) curvature sensor is proposed and investigated. The curvature sensing …

Unobtrusive and continuous monitoring of vital signs is becoming more and more important
both for patient monitoring in the home environment and for sports activity tracking. Even …

Fiber optic sensors based on fiber Bragg grating (FBG) technology have the potential to
revolutionize the way vital signs of the human body are measured and monitored. By …

A novel optical active fiber sensing technique based on the lasing wavelength demodulation
for monitoring the human pulse and respiration is firstly proposed and experimentally …

Fiber Bragg grating (FBG) sensors play a decisive role in clinical decisions, where their
ability to show chemical inertness, small in size, and high sensitivity makes them superior to …

Body temperature provides an insight into the physiological state of a person, and body
temperature changes reflect much information about human health. In this study, a garment …
