Novel moisture-absorbing film - Photo 2 (IMAGE) National University of Singapore Caption A team of researchers from the National University of Singapore invented a novel thin film that evaporates sweat six times faster and holds 15 times more moisture than conventional materials. In this prototype, the insole coated with the novel thin film turns from blue to pink as it absorbs moisture. The insole can be easily 'regenerated' by putting it under the sun, and be reused for more than 100 times.
