When it comes to X-ray devices you will find a surprising number machines which can easily penetrate into different kinds of materials to provide the desired effect. Two engineers Kaushik Sengupta and Ali Hajimiri from the California Institute of Technology (Caltech) have created a microchip that can turn any electric device into an X-ray tool.
The duo have radiated and generated electromagnetic waves of high frequency called terahertz (THz) with these small and low cost silicon microchips, which enables it to penetrate through a range of materials without causing any ionizing damage fromX-rays.
On top of that, these cheap silicon microchips portray high resolution images of various packaging. Also, the terahertz (THz) waves, which these microchips generate, can spot biological weapons, chemical fingerprints of pharmaceutical medicines, illegal drugs and explosives, which makes it a very crucial discovery.
With the help of these small and inexpensive microchips law enforcement agencies like homeland security and healthcare departments, wireless communication as well as the gaming industry can develop compact handheld devices that will not only replace the currently used big and costly laser setups of THz systems, but it will also produce better results than its predecessors.
Talking about their invention the designers of this microchip, Kaushik Sengupta and Ali Hajimiri told that they were “using the same low-cost, integrated-circuit technology that’s used to make the microchips found in our cell phones and notepads today, we have made a silicon chip that can operate at nearly 300 times their speed. These chips will enable a new generation of extremely versatile sensors.”
