See-Through Sensors
Among graphene’s remarkable properties are its electrical conductivity and capability of fabricating extremely thin structures. Knowing this, biomedical engineers at the University of Wisconsin-Madison were able to make a microelectrode neural implant that is only 4 atoms thick—i.e. thin enough to be transparent. Such a device allows neurologists to actually see what’s transmitting beneath the surface of the implant. They also envision similar implants for other organs. MORE
