Researchers in the US and South Korea have developed a chip with technology directly inspired by Superman's X-ray vision. Integrated into a mobile device, this chip could allow users to see behind walls or even inside a parcel.
Researchers from the University of Texas at Dallas in the US and Seoul National University in Korea have developed an imager chip capable of "scanning" the inside of a bag or parcel, or detecting solid objects on the other side of a wall. They are now concentrating on miniaturising the technology so that it can one day be integrated into a smartphone.
