Researchers at Binghamton University have developed wallpaper embedded with tiny moisture-electric generators (MEGs) that absorb humidity from indoor air and convert it into electrical current. The technology, designed with glycerol and polyvinylpyrrolidone structures, could power low-energy devices like environmental sensors and wireless devices while helping regulate room humidity.
A developer created Wet Bulb Tracker, an iOS app that sends alerts and forecasts for humid-heat conditions based on wet bulb globe temperature (WBGT), which measures how effectively the body can cool through sweating rather than just air temperature. The app uses color-coded risk levels from global health institutions and includes hourly timelines, forecasts, and Apple Watch integration to help users understand and prepare for dangerous heat-humidity combinations.
