Electricity-Harvesting Wallpaper: Power From Humid Air
Researchers at Binghamton University have developed a “moist-electric wallpaper” capable of harvesting electricity from indoor humidity to power small electronics. By using a series-parallel network of 1,596 generator units, the team produced roughly 3.5 volts at 38 percent humidity, which was sufficient to power a wireless keyboard in real time when paired with a capacitor. … Read more
