New 3D thermal invisibility cloak makes objects disappear from infrared cameras
Summary
Researchers developed a 3D invisibility cloak that redirects heat around an object, making it invisible to infrared cameras and thermally stable inside. The device is a 3D-printed aluminum lattice filled with a low-thermal-conductivity material, tested with infrared imaging to show undisturbed external temperature patterns. Potential applications include electronics cooling and stealth-related technologies.
