Elasto-magneto-electric (EME) sensors for force monitoring of prestressing tendons

Abstract Stress/force monitoring of prestressing tendons is challenging but crucial to the evaluation safety structures in which they are used. To this end, a smart elasto-magneto-electric (EME) sensor based on elasto-magnetic (EM) and magneto-electric (ME) effects proposed for noncontact field absolute stress these steel tendons. In paper, our research design, implementation, application EME sensory system non-destructive overviewed. The results confirm that developed possesses high repeatability, ease operation maintenance, corrosion resistance, long expected service-life. It demonstrated technology feasible stress/force both new existing reliable stable.
