Researchers at the University of California San Diego developed a wearable technology that can hide its wearer from heat-detecting sensors such as night vision goggles, even when the ambient temperature changes–a feat that current state of the art technology cannot match. The technology can adapt to temperature changes in just a few minutes, while keeping the wearer comfortable.
The device, which is at the proof-of-concept stage, has a surface that quickly cools down or heats up to match ambient temperatures, camouflaging the wearer’s body heat. The surface can go from 10 to 38 degrees Celsius (50 to 100.5 degrees Fahrenheit) in less than a minute. Meanwhile, the inside remains at the same temperature as human skin, making it comfortable for the wearer. The wireless device can be embedded into fabric, such as an armband. A more advanced version could be worn as a jacket.
