At The University of Texas in Dallas, a team of researchers has found a way to make the section between microwaves and infrared light usable by medical or consumer devices. Just as infrared light can be viewed by some night vision goggles, devices that can image the terahertz band could see through drywall, wood, or even skin. It`s been possible to use this band before, but the new solution is cheaper and simpler to create. 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. There could definitely be some privacy implications, so for now they`re focusing only on imaging from about four inches away.
What do you think of this new type of technology? I personally find it a bit scary that the future could have people being able to look through walls of my house! But at the same time I see how it could be useful to businesses to check money for counterfeiting or quickly checking for problems like tumors.
