Contact lenses sharpen our blurry vision, and free us from the hassle of pushing sliding glasses back up our noses. But the future of contacts is nigh: Researchers have created a super-thin infrared sensor that could lead to the development of night vision contact lenses. Night vision, presently, is a rather clunky technology — epitomized in the rainy Tyrannosaurus rex scene in the original Jurassic Park
. To see in the dark, a person dons a set of binocular-shaped goggles strapped to the head. The devices also produce a lot of heat, so they need to be cooled, adding to the overall volume of mechanics required. Now, researchers from the University of Michigan are close to packing night vision’s clumsiness into technology that fits on your fingertip. They built a super-thin infrared light sensor using graphene — a material that’s a single carbon atom in thickness — that could be ...
