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 ...

Fig. 1 Overview of the OFN sensor. (A) Schematic diagram of the OFN sensing system; (B) Photographs of the output light when the sensor was untouched, (C) subjected to normal force, and (D) subjected ...

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.

A specially equipped Volvo VHD 430 totes a Sideway-force Coefficient Routine Investigation Machine (SCRIM) – to evaluate friction on roadways to determine whether highway improvements could reduce ...
