Fiber Bragg Grating Sensor for Structural Health Monitoring (SHM) in Vital Signs and Respiratory Parameters

Optical fiber Bragg grating (FBG) sensors have already proposed attractive capabilities for many applications. Considering the importance of such sensors in this study, the FBG fabrication techniques, Bragg grating types, and different models of FBG structures described. A description of the biomedical FBG sensors are also given here. Considering such applications, some simple setups proposed based on the FBG sensors for the vital and respiratory signs monitoring as a type of structural health monitoring (SHM) that show interesting results for the various case studies. Empirical results for the two different setups are proposed and compared in this report.
