Abstract:
In the last decades, fiber Bragg gratings (FBGs) have become increasingly attractive to medical
applications due to their unique properties such as small size, biocompatibility, immunity to electromagnetic
interferences, high sensitivity and multiplexing capability. FBGs have been employed in the development
of surgical tools, assistive devices, wearables, and biosensors, showing great potentialities for medical uses.
This paper reviews the FBG-based measuring systems, their principle of work, and their applications in
medicine and healthcare. Particular attention is given to sensing solutions for biomechanics, minimally
invasive surgery, physiological monitoring, and medical biosensing. Strengths, weaknesses, open challenges,
and future trends are also discussed to highlight how FBGs can meet the demands of next-generation medical
devices and healthcare system
