Abstract
Official abstract text for this publication.
A corrosion detection sensor embedded within a concrete structure. The sensor includes a hermetically sealed resonant circuit that is a resistor-inductor-capacitor (RLC) circuit. The sensor further includes a sacrificial transducer that is inductively or capacitively coupled to the resonant circuit, where the sacrificial transducer is exposed to an environment outside the sensor to monitor corrosion of steel reinforcement in the concrete structure. Additionally, the sensor includes a protective cementitious housing surrounding the resonant circuit and the sacrificial transducer. The sensor further includes a diffusion layer placed over the sacrificial transducer, where the diffusion layer enables a dispersion of a chemical species over the sacrificial transducer. In this manner, a more uniform distribution of the chemical species over the surface of the sacrificial transducer mitigating the localized corrosion is ensured. Furthermore, such a design is less susceptible to false positives.
