Development of Autonomous UHF RFID Sensors Embedded in Concrete for the Monitoring of Infrastructures in Marine Environments

Abstract

Chloride ingress in reinforced concrete infrastructures is of crucial importance when considering structural health monitoring applications in marine environments. It indeed leads to the depassivation and corrosion of steel and hence to the degradation of the whole infrastructure. The present study reports the development of an embedded wireless autonomous sensor dedicated to the monitoring of corrosivity of concrete initiated by such ingress. The sensor is based on the ultra high frequency (UHF) radiofrequency identification (RFID) technology. The communication between a commercial RFID reader and a specific optimized embedded antenna in concrete is experimentally demonstrated. In the last part of the study, a resistive corrosion sensor connected to the RFID chip is proposed for the evaluation of chloride ingress.
