A ski jacket that actively gets rid of

To keep the body warm and dry during winter sports, high-performance clothing is a must. The demands on these textiles are high, as a person sweats up to one liter per hour on his upper body alone when skiing. A new technology, co-developed by a team of Empa scientists, helps athletes sweating by actively transporting moisture away from the body and to the outside. This is possible because ultra-thin layers of gold in the fabric are electrified. Man is a warm-blooded animal. If it gets too hot for him, he can tune down his body temperature. This feat is achieved by an evolutionarily refined "AC system" in our skin: the sweat glands.
