Humidity-Harvesting Wallpaper Can Power Small Devices Indoors
Scientists created a wallpaper-like material that generates electricity from humidity in indoor air. The wall covering powered a wireless keyboard while also absorbing excess moisture. It suggests a possible way to harvest energy from ordinary home environments.
Researchers have demonstrated a wall-covering material that turns moisture in indoor air into usable electricity. In their test, it operated a wireless keyboard, showing that small electronics might run on ambient humidity. The same material also took up surplus moisture. This points to a broader idea: ordinary rooms may contain untapped energy resources, and building surfaces could potentially serve dual roles as decor and power sources.
If such materials become practical, households and office occupants could gain a passive way to power low-demand devices, potentially reducing reliance on batteries or cords for some items. Manufacturers and building designers may see new options for integrating energy harvesting into interiors. Near-term effects may remain limited to niche applications, since real-world performance and adoption are uncertain.
