Walabot is a handheld 3D-imaging device that plugs into your Android phone and allows you to see through walls, objects, and materials. The parent technology, Vayyar, was originally developed for breast cancer screening, providing something much more portable than a mammogram machine, and making it cheaper, easier, and safer for women to be scanned. But the makers believe there are many more potential applications.
“Looking into skin tissue is difficult,” explained Malcolm Berman, director of marketing at Vayyar, in an interview with Digital Trends. “If you can see through that, then you can see through many other things.”
The 3D imaging is created using radio frequency technology, the same technique we use for Wi-Fi, mobile networks, and radar systems. Vayyar is able to use RF to see through solid objects and Berman claims it emits a fraction of the radiation that our cellphones do. There are antennas in the Walabot firing out signals and sensors to pick up the reflections.
