Sweating is not really pleasant, but it’s a normal, natural way for the human body to regulate body temperature by decreasing thermal stress, which can occur for a number of reasons, including exercising, high temperatures, eating spicy food, or when you’re experiencing anxiety or embarrassment.


Researchers from the National University of Singapore ( NUS ) created a novel film that can evaporate sweat six times faster and use the harvested moisture to power wearable electronic devices . They recently published a paper about their work, titled “ Super-hygroscopic film for wearables with dual functions of expediting sweat evaporation and energy harvesting, ” in the scientific journal Nano Energy , and 3D printed a prototype product for what seems to be a very helpful application. The abstract states, “Despite the boom in atmospheric water-harvesting techniques, few attempts have been made with a broader horizon–absorbing the moisture from sweatevaporation, which has substantial implications for human comfort and wearable electronics. Herein, a cobalt-complex-based super-hygroscopic material (Co-SHM) is developed to expedite sweat evaporation and fabricate moisture-triggered energy harvesting devices. The Co-SHM features transparent thin-film structure, fast absorption kinetics and high water uptake of 4.6 g g −1 . The material regeneration can be […]
