As we all know human body radiates energy in the electromagnetic waves in the infrared spectrum. Like in summer human body radiates a lot of energy so to oppose this infrared-blocking covers are used to minimise the energy loss from the body. The best example of this is Emergency blankets.
By the next step of this technology is to use for dynamic thermal management of earth-orbiting satellites as satellite face a lot of temperature change. By this technology, the temperature of the satellite can be regulated.
