Abstract

The study focuses on the formation of artificial neural pathways for the use of structural health monitoring in prosthesis by means of Fiber Bragg Grating (FBG) optic sensors to detect shifts in strain. Implementation of these fibers are embedded into carbon fiber reinforced polymer (CFRP) based structures. CFRP was considered for its wide use application in ankle-foot prosthesis, which undergoes high loads of stress and wear.. This method acts as a system of early detection which could prevent the prosthesis from critical failure due to previously undetected interior defects, further improving the patient’s well being.
