New 3D-printed ‘invisibility’ cloak can hide objects from infrared cameras

Researchers at the University of Illinois Urbana-Champaign have created the first 3D-printed thermal "invisibility" cloak that hides objects from infrared cameras at any angle. Unlike older designs, it guides heat around objects rather than blocking it, erasing thermal signatures completely. Potential uses include protecting military vehicles from heat-seeking sensors and managing heat in microchips. Future versions may dynamically respond to internally generated heat.
