See at Night Like "Predator" with Graphene Contact Lenses
"Graphene could make it possible to build ultra-thin, flexible thermal sensors for built-in night vision technology — just like that lethal alien in the Predator franchise," notes Gizmodo. "Modern night-vision equipment exploits the generation of heat by living bodies by focusing the thermal emissions with a special lens. The signal is then transmitted to IR detectors, which create a detailed pattern based on variations in temperature. That so-called thermogram is then turned into electrical impulses, which a computer analyses and sends to the display. The end result: the user sees that data represented as various colours, depending on the intensity of the IR emission." Read more.
