Researchers invent self-charging, ultra-thin device that generates electricity from air moisture

A team of researchers from the National University of Singapore’s (NUS) College of Design and Engineering (CDE) has developed a new moisture-driven electricity generation (MEG) device made of a thin layer of fabric - about 0.3 millimetres (mm) in thickness - sea salt, carbon ink, and a special water-absorbing gel.
Using sea salt as an eco-friendly moisture absorbent, this rechargeable fabric-like ‘battery’ provides higher electrical output than a conventional AA battery - potentially powering everyday electronics.
