Scientists on 24 June 2014 developed new sensing skin technology that can detect cracks in concrete structures.
Scientists from North Carolina State University and the University of Eastern Finland have developed the technology.
The technology will allow the authorities to respond quickly to damage in everything from nuclear facilities to bridges.
How it detects the crack in concrete structures
The sensing skin is painted onto the structure, over the electrodes. A computer programme then runs a small current between two of the electrodes at a time, cycling through a number of combinations.
Every time the current runs between two electrodes, a computer monitors and records the electrical potential at all of the electrodes on the structure. This data is used to calculate the sensing skin's spatially distributed electrical conductivity. If the skin's conductivity decreases, it means the structure is damaged.
About Sensing Skin Technology
The skin is an electrically conductive coat of paint that can be applied to new or existing structures. The paint can incorporate any number of conductive materials. It will make the skin inexpensive. Electrodes are applied around the perimeter of a structure.
