Liquid gears promise wear-free robotics, NYU study shows

NYU researchers developed a fluid-based gear system that transmits motion via directed fluid flows instead of interlocking teeth, enabling non-contact transmission and reducing wear and jam risks. Demonstrated with two submerged cylinders in a water–glycerol mix, the approach could inform soft robotics and instantly tunable gear ratios, with findings published in Physical Review Letters.
