Abstract

An optical fibre-based strain sensor “stitched” to a functionalised carbon structure (FCS) that can be used for structural health monitoring is introduced. The aim of the design is not only to monitor strain, but also to strengthen the structure. The integration of optical fibres on FCS is achieved by “interweaving” the two elements on a polymer textile substrate using a specialised fabrication process. The sensor was then characterised using a fibre-optic Mach-Zehnder interferometric setup. Two different functionalised skein samples (incorporating optical fibres) were tested and a good correlation between the applied force and measured length change was observed.
