Heat Cloak Hides from Thermal Cameras

Heat Cloak Hides from Thermal Cameras
An innovative coating able to cloak thermal radiation offers a level of detection against thermal cameras.

The new, ultrathin coating created by the teams from Purdue, Madison-Wisconsin, MIT and Brookhaven is made up of the tunable material samarium nickel oxide, which breaks the relationship between heat and light. Though objects typically grow brighter at higher temperatures, the light emitted by the new coating will reduce at a specific temperature range—rendering any objects beneath invisible to thermal cameras.

The team believes the coating could be used to create a sort of personal privacy shield, wrapping around cars or incorporated into clothing to confuse infrared cameras.

Interesting would also be a partial or fake thermal visibility.
