To study fine touch, selecting samples based on how many mechanical instabilities they can form is more predictive than using the friction coefficient, which has been the default choice.

Haptic feedback in tactile displays has emerged as a crucial technology in bridging the gap between virtual and tangible experiences. By modulating friction through techniques such as electrovibration ...

Avoid common pitfalls when calculating work done by friction! This video highlights the most frequent mistakes students make, from misinterpreting frictional forces to applying formulas incorrectly.
