Magnetoelastic sensor application in civil buildings monitoring

Abstract The development of a novel magnetoelastic sensor, based on the stress influence on amplitude of the resonant mechanical waves inside a Fe 62.5 Co 6 Ni 7.5 Zr 6 Cu 1 Nb 2 B 15 ribbon, for strain and/or stress real-time monitoring in civil buildings is reported. This novel sensor exhibits better sensitivity than resistive and vibrating wire strain gauges, good reliability and stability.
