Paint That Glows When The Structure Is Stressed

Researchers at #-Link-Snipped-# have come up with a nanotube-filled 'strain-paint', that gets engineers attention to the stresses/compression by glowing in infrared light. Traditional stress sensors like those used in aircrafts do help, but their help is quite limited in areas where they have to render an image of the airplane's structural strength. Simply put, they just compute the commonly cased strains and don't describe the obscure ones.

The Rice strain paint is able to depict stress over a complete area and in all directions, sans the inspector being in close proximity of the object being examined. It operates through a long-ago found attribute of semiconducting carbon nanotubes that originates ruined nanotubes to blush fluorescent in the presence of an almost infrared light. This paint will even work on static structures like bridges and dams. The paint is not commercially available in the market as yet, as more analysis is left to be done. But developments are underway to render the strain paint with anti-corrosive and heat-repelling properties.
