Researchers from New York’s Binghamton University have developed a wallpaper that generates electricity from the air. The technology is called Moist-electric generators, which have existed for years, but is now closer to becoming practical.

EXCERPT:
Wallpaper indoors holds an aesthetic value. Other than that, they don’t do much. But a new wallpaper-style device could pull electricity from the moisture already present in the indoor air. At the same time, it also acts as an indoor climate regulator; it absorbs excess moisture from the room and also releases stored moisture to increase humidity.
The study transforms a single sheet of wallpaper into a humidity-responsive platform that not only harvests energy but also helps maintain indoor climate, the researchers say. They also add that this new wallpaper can fuel low-power-demanding gadgets like sensors or wireless modules.
Moist-electric generators (MEGs) are devices that convert humidity into electricity. They have been around for years and have emerged as a reliable energy-harvesting source without an external fuel source. But most of the previous generators have focused on outdoor humidity, “because there is a lot of moisture out there that is an excellent energy resource,” says Seokheun Choi of Binghamton University.
