Graphene Gives You Infrared Vision in a Contact Lens
It sounds like something from a spy thriller movie: putting on a contact lens that gives you infrared vision without a bulky contraption that covers your face. But now, thanks to research at the University of Michigan, such a contact lens is a real possibility.

The Michigan researchers turned to the optical capabilities of graphene to create their infrared contact lens. IBM last year demonstrated some of the photoconductivity mechanisms of graphene that make it an attractive infrared detector.

Graphene is capable of detecting the entire infrared spectrum, with visible and ultraviolet light thrown in. But where graphene giveth, it also taketh away. Because graphene is only one-atom thick, it can absorb only 2.3 percent of the light that hits it. This is not enough to generate a electrical signal, and without signal it can’t operate as a infrared sensor.
