Researchers at Princeton University have built a new type of sensor that could help engineers quickly assess the health of a building or bridge. The sensor is an organic laser, deposited on a sheet of rubber: when it's stretched?by the formation of a crack, for instance?the color of light it emits changes. "The idea came from the notion that perhaps it's possible to cover large structures like bridges with a skin that you can use to detect deformation of the structure from a distance," says Sigurd Wagner, professor of electrical engineering at Princeton University, who developed the stretchable laser sensor with and Patrick G
