Composite gear design at igus is proving that lightweight, smart and maintenance-free solutions are the future of industrial motion. Machine Design checked in at the igus booth at Pack Expo to speak ...

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.

"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, perform periodic movements and control microscopic ...
