Abstract

The need for structural health monitoring, or the use of in-situ continuous measurement of structural operating parameters, was initially implemented in the fields of aerospace and civil engineering composites. Fiber optic sensors (FOS) are considered for these methods due to their high durability, negligible impact on embedded materials, insensitivity to electromagnetic fields, accuracy, and low cost. Our 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. Then tested using an industrial interrogator and analysis software to acquire preliminary data. CFRP was considered for its wide use application in lower limb prosthesis, particularly that of ankle-foot prosthesis. 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.
