Following the breakthrough with their first sweating artificial skin two years ago, Danqing Liu's multidisciplinary team hasn't been sitting still. Their goal: an artificial skin that sweats as naturally as possible. They have succeeded in this, as can be read in their article in Angewandte Chemie. There, they explain how they managed to be the first team in the world to be able to accurately control where, when and how much an artificial skin sweats and also where the liquid collects.
