Future Smartphones May Be Able To See Through Walls

Researchers at the University of Texas at Dallas have managed to come up with an idea to enable future smartphone owners to share the same trait as Superman - namely, the super power to be able to see through walls.

The researchers made two scientific breakthroughs, allowing them to develop devices capable to see through objects.

The discovery made by the Professor of Electrical Engineering, Dr. Kenneth O, and his team, relies on the terahertz band of the electromagnetic spectrum. This wavelength of energy can go through objects, much like that of X-rays.

Dr. Kenneth O also used a new type of consumer grade microchip, based on CMOS technology. A sensor in the chip captures the terahertz signals and generates images.

"The combination of CMOS and terahertz means you could put this chip and receiver on the back of a cellphone, turning it into a device carried in your pocket that can see through objects," explained Dr. O.

The applications of this technology are used within a wide range of industries, from medicine to detecting counterfeit money - and would also prove to be a useful tool for any wannabe spy. However, In order to prevent intrusive people breaching the privacy of others, the technology will not work if used more than 4 inches (10 cm) away from its target.
