Microchip Gives Phones X-Ray Vision to detect harmful materials

Engineers at Caltech have developed a microchip that can act as an X-ray tool for any electric device. PSFK reports.

While easily penetrating packaging materials and rendering image details in high resolution, and the THz waves can also detect the chemical fingerprints of pharmaceutical drugs, biological weapons, or illegal drugs or explosives.quotesmarksleft.jpg
