Self-Powered Wireless Corrosion Monitoring Sensors and Networks

This letter introduces a kind of new idea for corrosion monitoring of reinforcing concrete structures with the techniques of electrochemical reactions and wireless sensor networks in civil engineering. The electrochemical noise generated by corrosion is used not only as sensing signal but also as energy source for a wireless sensor. The research is preliminary, the realization of the self-powered wireless corrosion monitoring sensors and networks can be considered as a milestone in the field of structural health monitoring.
