A low-cost smart paint detects microscopic faults in wind turbines, mines, and bridges before structural damage occurs. The environmentally-friendly paint uses nanotechnology to detect movement in large structures, and could shape the future of safety monitoring.

The paint is formed using a recycled waste product known as fly ash and highly aligned carbon nanotubes. When mixed, it has a cement-like property which makes it particularly useful in harsh environments.
