Thanks to a new energy harvesting and storage technology developed by the mechanical engineers at the University of Wisconsin-Madison.
This technique can reduce reliance on batteries in mobile devices and charge your smartphone as you walk.
Human walking carries a lot of energy.
A typical smartphone requires less than two watts of energy.
The process the team is working on now is known as reverse electrowetting.
This technique uses a conductive liquid that works with a nanofilm-coated surface that is able to produce electricity.
Researchers developed a bubbler method, which combines reverse electrowetting with bubble growth and collapse.
The tiny holes in the bottom plate allow pressurized gas to enter and form tiny bubbles.
The findings were published in the journal Scientific Reports.
The engineers are looking for industry to commercialise the technology through their startup company, InStep NanoPower.
