Computer chips that operate in the terahertz range of the radio spectrum could be used by smartphones to turn your phone into the equivalent of a portable x-ray machine. Actually, terahertz frequencies provide better images than conventional x-rays and don’t damage tissue.
The technology is already being used by law enforcement and security applications, but currently the equipment used is relatively bulky. However, a team at the California Institute of Technology has built a microchip that can both transmit and receive terahertz radiation, opening the door for the mobile equivalent of an x-ray.
