Optical fiber sensors in orthopedic biomechanics and rehabilitation

We report on the application perspectives of optical fiber strain and shear sensor configurations in the fields of orthopedic biomechanics and rehabilitation. The principle of operation of Fiber Bragg Grating (FBG) sensing elements is presented revealing their potential for introducing intelligence in biotechnological products for orthopedics and rehabilitation. Finally, we present recent advances in the development of fiber sensing structures for utilization in Human Machine Interfaces (HMI) employed in clinical beds, amputee sockets and wheelchair seating systems, targeting pressure ulcer and wound treatment.
