Scientists make film that absorbs sweat's moisture, helps power devices
NUS scientists have developed a film that is "extremely effective in evaporating sweat" from the skin and then absorbing the moisture from sweat. The film can rapidly release water on exposure to sunlight and can be "regenerated" and reused for more than 100 times. Scientists also made a wearable energy harvesting device comprising eight ECs, using the film as electrolyte.
