Sensitivity Enhanced and Noises Suppressed Double-Fish-Tail-Shaped Fiber Bragg Grating Sensor for Heart Rate Monitoring

Wearable fiber Bragg grating (FBG) sensors offer attractive advantages for physiological monitoring. However, the weak strain generated by respiration and cardiac activity and the susceptibility to laser intensity noise and motion-induced disturbances remain major challenges. In...
