A special coating that can hide its own temperature from thermal cameras has been developed by researchers from the US. The technology relies on the temperature-dependant reflective properties of vanadium oxide, a material that undergoes extreme electronic changes at a specific temperature. When heated from room temperature to 80 °C, the material’s thermal radiation rises normally up until 74 °C, before suddenly appearing to drop to around 20 °C colder than in reality. The rather surprising result could have potential military applications, including camouflage, be used in communication systems and help with future metamaterial research…………
