Forget X-Ray Vision. You Can See Through Walls With Radio
12th June 2018
Of course, X-ray vision would come with a downside, in that you’d be spraying all your surveillance targets with radiation. So researchers at the MIT Computer Science and Artificial Intelligence Laboratory, actualizers of all things science fiction, have taken a different tack to seeing through walls: radio waves. By flinging ultra-low-power radio signals, 1,000 times milder than standard Wi-Fi, they can not only detect humans behind a wall, but track their movements in fine detail.
