Ball screws have become an indispensable key transmission component in modern precision manufacturing. They convert ...

Based on differences in friction characteristics, screws are primarily classified into three categories: sliding screws, rolling screws, and hydrostatic screws. Among these, rolling screws are widely ...

Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic dimensions has stumped engineers for decades.

Breakthrough “metamachines” show how beams of light can drive gears and levers smaller than a grain of dust—opening doors to ...

The Gothenburg solution employed optical metamaterials to create mechanisms that operate under uniform illumination, offering a more versatile platform for precise control and movement of functional ...

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the ...

Researchers from Massachusetts Institute of Technology (MIT) and University of Chemistry and Technology Prague created a ...

Gears are everywhere – from clocks and cars to robots and wind turbines. For more than 30 years, researchers have been trying to create even smaller gears in order to construct micro-engines. But ...

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 ...

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 ...
