Abstract: This report summarises our recent research progresses in developing new distributed sensing technologies for structural health monitoring (SHM) based on the new microwave-photonic and coaxial cable platforms. The two new platforms have the combined advantages of high measurement resolution, large strain capability, long span of coverage, easy-to-install/embed, spatial continuity (no dark zones), and flexible gauge lengths. The new distributed sensing technology may bring a revolutionary tool to address a number of insufficiently-studied areas in SHM, such as distributed monitoring of cracks and corrosion, post seismic monitoring to ensure mission-critical services in disaster responses and emergency evacuations, study of the progressive structural failures/collapses under extreme loads, and high performance smart structures.

Keywords: distributed sensor; microwave-photonics; coaxial cable; structure health monitoring; SHM.
