We've seen scientists explore a number of ways to make paint "smarter" over the years, and now a team of researchers at the University of Strathclyde in Glasgow have devised a method that they say could do nothing short of "revolutionize structural safety." The key to that is some novel nanotechnology that effectively turns the paint into a sensor network that's able to detect minor structural faults before they become a severe problem. More specifically, the paint consists of a mix of highly aligned carbon nanotubes and a recycled waste material known as fly ash -- when the nanotubes bend, the conductivity changes, indicating that there could be a structural problem developing. What's more, the fly ash is also said to give the paint a cement-like structure, which the researchers say could let it be used in harsh conditions where traditional structural monitoring can prove difficult (and expensive).
