Would you find moisture-powered wallpaper useful for managing electronics in your home?

Binghamton University researchers have created a moisture-electric wallpaper that generates electricity from humidity. The system successfully powered a wireless keyboard during a recent scaling test.

Why it matters

This innovation offers a potential method to power sensors and low-power electronics by harvesting energy directly from indoor environments. By utilizing moisture-electric effects, the material transforms atmospheric water vapor into a sustainable electrical current.

The generator consists of 2-by-2-centimeter chromatography paper squares with a peak power density of 2.2 microwatts per square centimeter. A 28-unit array reduced sealed chamber humidity from 75 percent to 50 percent in four minutes.

The players

Binghamton University

This public research university located in Binghamton, New York, serves as the home for the research team that developed the new wallpaper technology.

The details

The device uses glycerol-coated edges to absorb water vapor, which then travels toward the center of the paper as liquid before leaving through wax-treated pores. This process ensures one-way flow, creating a steady charge that powered the keyboard.

2015: Graphene oxide study demonstrated electricity generation from humidity.
2020: Researchers reported power production from protein nanowires.
2023: Joule study demonstrated fully printed moisture generator arrays.
2024: Nature Reviews Materials published a perspective on moisture energy.

The Big Picture

This development follows a pattern set by the 2023 Joule study on fully printed moisture generator arrays. It signifies a continued shift toward scalable, paper-based materials for low-power energy harvesting applications.

This technology could eventually lead to self-powering sensors that remove the need for batteries in home automation devices. Future iterations may see the material integrated into standard wall coverings to provide passive power for low-energy smart electronics.

The takeaway

Harvesters that utilize ambient humidity can provide a constant source of power for small electronics without needing external charging. Homeowners should track future developments in paper-based energy for potential applications in sustainable smart home design.
