'Smart paint' can warn of structure faults

GLASGOW, Scotland, Jan 30, 2012 -- UPI

 

Researchers in Scotland say a new low-cost "smart paint" can detect microscopic faults in wind turbines, mines and bridges before structural damage occurs.

Scientists at the University of Strathclyde in Glasgow say the paint uses nanotechnology to detect movement in large structures and can be simply sprayed onto any surface with electrodes attached to detect structural changes long before failure occurs.

"The development of this smart-paint technology could have far-reaching implications for the way we monitor the safety of large structures all over the world," researcher Mohamed Saafi said in a university release Monday.

The paint contains a recycled waste product known as fly ash and highly aligned carbon nanotubes in a cement-like combination particularly useful in harsh environments, he said.

"There are no limitations as to where it could be used and the low-cost nature gives it a significant advantage over the current options available in the industry.

"The process of producing and applying the paint also gives it an advantage as no expertise is required and monitoring itself is straightforward," he said.
