The “nanogenerator” can currently capture enough energy from light breezes, such as those created by a brisk walk, to power 100 LED lights and temperature sensors.
It is made of two plastic strips, which become electrically charged when they flutter in the wind through a process called the triboelectric effect - commonly observed by rubbing one’s hair with a balloon.
The “low-cost" device is thought to be the most efficient nanogenerator yet created.
While a breeze as gentle as 3.6 miles per hour was enough to power the nanogenerator, it performs at its best when wind velocity is between nine and 18mph - a speed allowing the two plastic strips to flutter in sync, results published in the journal Cell Reports Physical Science showed.
“You can collect all the breeze in your everyday life,” said senior author Dr Ya Yang, of the Chinese Academy of Sciences.
“We once placed our nanogenerator on a person's arm, and a swinging arm's airflow was enough to generate power.”
Dr Yang has two differing hopes for the technology.
The first goal is to make it more efficient in order to create an endless, sustainable energy supply for small mobile devices.
“We have designed a nanogenerator as small as a coin, but we want to make it even tinier and more compact with higher efficiency,” Dr Yang said.
The second aim is to complement wind turbines in harnessing the winds they currently cannot reach.
“I'm hoping to scale up the device to produce 1,000 watts, so it's competitive with traditional wind turbines,” he said. “We can place these devices where traditional wind turbines can't reach. We can put it in the mountains or on the top of buildings for sustainable energy.”
The UK has over 10,000 wind turbines, each of which can cost anywhere from £350,000 to £3m.
“Unlike wind turbines that use coils and magnets, where the costs are fixed, we can pick and choose low-cost materials for our device,” Dr Yang said.
"Our device can also be safely applied to nature reserves or cities because it doesn't have the rotating structures."
While nearly 9,000 of the UK's turbines are onshore, offshore turbines are far more productive.
“Our intention isn't to replace existing wind power generation technology,” Dr Yang added. “Our goal is to solve the issues that the traditional wind turbines can't solve.”
