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

Researchers have developed a new moisture-driven electricity generation device made of a thin layer of fabric, sea salt, carbon ink, and a special water-absorbing gel. The device works by keeping one end of the fabric dry, while the other end is perpetually wet. The difference in moisture content of the wet and dry regions of the carbon-coated fabric creates an electric current. This rechargeable fabric-like battery can produce electricity for more than 150 hours and provides higher electrical output than a conventional AA battery, potentially powering everyday electronics.
