Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...

Friction is the enemy of all things mechanical, and without regular maintenance, machinery service life becomes severely reduced until, ultimately, the machines cease to function. Anyone who owns a ...

Recently, the Li Faxin Research Group of Peking University College of Engineering developed the world's first dynamic mechanical analyzer (DMA) suitable for hard materials (metals, ceramics, etc.), as ...

A new portable, space-saving bench system has been designed for accurate measurement of friction pressure in slick water ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
