This Wallpaper Generates Electricity from the Air
Researchers at Binghamton University in New York have developed a type of wallpaper that generates electricity from moisture in the air. It doesn't need sunlight or an electrical outlet, and although the amount of power it produces is small, the technology could eventually have some surprisingly practical uses around the home.
The wallpaper contains hundreds or even thousands of tiny generators made from specially treated paper. Each absorbs water vapor from the surrounding air and directs it through the material. As the moisture moves, it creates an electrical charge. The water eventually evaporates back into the air, allowing the process to continue.
The generators are connected by wiring concealed behind the wallpaper, so future versions could look much like ordinary wall coverings.
What Could It Power?
Not your refrigerator or television, but researchers have already demonstrated that the wallpaper can power small electronic devices.
In one experiment, a panel containing 1,596 tiny generators produced enough electricity to operate a wireless keyboard with the help of a device that stores electrical energy. A smaller arrangement powered a humidity sensor for approximately 15 minutes.
This could be particularly useful for homeowners who rely on electronic sensors to monitor conditions around their homes. Temperature and humidity sensors in attics, crawl spaces, or other hard-to-reach locations might someday operate without batteries that need regular replacement. The technology could also have applications for other low-power smart-home devices.
Could It Help Control Humidity, Too?
During testing, researchers discovered another interesting benefit: their larger wallpaper panel reduced the surrounding air's relative humidity from 38% to 32%.
Although much of the absorbed moisture eventually evaporates back into the air, the wallpaper can temporarily retain some of it. This raises the possibility that future versions could help moderate indoor humidity levels, although researchers haven't yet demonstrated sustained humidity control in an occupied home.
For now, electricity-generating wallpaper remains experimental. Scientists still need to improve its power output and determine how practical and affordable it would be for everyday use.
This research offers an intriguing glimpse of what may be ahead. Wallpaper has traditionally been chosen for its appearance. Someday, it might be doing a little work for us, too.
