Graphene could bring night vision to phones and cars
Thermal imaging devices like night-vision goggles can help police, search-and-rescue teams and soldiers to pick out bad guys or victims through walls or in complete darkness. However, the best devices require cryogenic cooling, making them heavy, expensive and slow. Enter graphene, the semi-conducting material that’s 100 times stronger than steel — researchers from MIT have built a chip out of the material that may solve the problem. The resulting infrared sensors were small enough that they could be “integrated in every cellphone and every laptop,” according to the study’s co-author, Tomas Palacios.
