Laser-activated nanotube skin shows where the strain is

Whether they're in airplane wings, bridges or other critical structures, cracks can cause catastrophic failure before they're large enough to be noticed by the human eye. A strain-sensing "skin" applied to such objects could help, though, by lighting up when exposed to laser light.
