A new research project aims to address the rising costs associated with maintaining and repairing critical infrastructure such as the Great Belt Bridge and the Limfjord Tunnel. The new type of monitoring, Structural Health Monitoring (SMH systems), increases the safety and lifespan of structures while reducing CO2.
Constant monitoring of corrosion on large concrete structures using a wireless sensor network that can power itself. This is the goal of a new project totaling DKK 35 million, in which Innovation Fund Denmark has invested DKK 26 million.
Currently, corrosion sensors rely on so-called electromechanical techniques, which are expensive to install because they need to be molded into the structure, require extensive cabling, and can only monitor a few critical areas. In addition, measurements typically have to be performed manually, often in hard-to-reach places…
