An Invisibility Cloak for Heat

Infrared sensors are able to peer into the night and see people in complete darkness because people give off body heat. But what if a person could wear clothing that makes their body heat silhouette invisible to infrared lenses?

Scientists in France are working on an invisibility cloak for heat and have reported their research in a recent issue of Optics Express. The technology could be used for military purposes to hide soliders from infrared detectors, but it could also work to thermally isolate circuits in computer chips, which would keep them cool.
