Fiber Bragg grating sensors for biomedical applications

Abstract

Given their EM immunity, intrinsic safety, small size & weight, autoclave compatibility and capability to perform multi-point and multi-parameter sensing remotely, optical fibers and fiberoptic-based sensors are seeing increased acceptance and new uses for a variety of bio-medical applications—from laser delivery systems, to disposable body temperature sensors, to intra-aortic catheter probes. This paper will review the benefits, needs and applications of fiber Bragg grating-based sensors in the bio-medical field.
