“We have built a gear train in which a light-driven gear sets the entire chain in motion,” explains lead author Gan Wang, a ...

The researchers are thus close to creating micromotors. "We have built a gear train in which a light-driven gear sets the entire chain in motion. The gears can also convert rotation into linear motion ...

Learn how the smallest motors in history could soon make a splash in healthcare thanks to microscopic gears that are powered ...

Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic ...

Scientists create microscopic gears powered by light, a breakthrough for chip-scale machines—promising, but still far from ...

Gears are fairly straightforward way to couple rotational motion, and the physics topics required to understand them are encountered in an entry level physics classroom, not a university degree. But ...

A mind-bogglingly small new motor can fit inside a strand of hair. Its cell-sized gears are powered by light and could be used as pumps inside the human body. Researchers at the University of ...
