Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic ...

Electrically tunable ionic hydrogels use small voltages to switch friction at metal contacts between high-friction and ultra-low-friction states, enabling voltage-programmed grip, release and motion ...
