Researchers create 3D thermal cloak to hide objects from infrared cameras
University of Illinois at Urbana-Champaign researchers developed a new 3D thermal invisibility cloak that hides objects from infrared cameras on October 26, 2026.
Heat guides around hidden items
The device directs heat flow around an object instead of blocking it. This method allows the item to remain invisible to thermal imaging from virtually any direction. Previous designs were limited to two dimensions or required specific heat travel paths.
Testing confirms extreme temperature protection
Scientists successfully built and tested the cloak while exposing it to severe cold and heat conditions. The technology safeguards delicate electronics and could improve cooling systems for microchips. Infrared cameras show a temperature pattern that makes the concealed object appear absent.
