Smart, Self-Powered Patch to Put an End to €2.3 trillion Bill Caused By Rust Worldwide


The cost of corrosion runs to 3-4 per cent of the gross world product (GWP) annually, and therefore there is increasing international focus on monitoring infrastructure projects. The Department of Engineering at Aarhus University is developing a smart patch that can cut huge amounts off the costs of rust.Globally, corrosion is an enormous problem. It is estimated that approx.

USD 2.5 trillion (approx. EUR 2.3 trillion) is spent annually on remediating rust problems, amounting to about 3-4 per cent of the GWP. Researchers from the Department of Engineering, Aarhus University, are developing a cheap, intelligent, self-powered, built-in patch that continuously monitors corrosion and steel reinforcement integrity in concrete structures. The goal is simple and cheap structural health monitoring everywhere.
