  • Friction involves a complex set of phenomena spanning a large range of length scales, but experiments assessing the evolution of the slip-front between two dry sliding bodies now reveal that slip can be reasonably well described by linear fracture mechanics theory.

  • Will a sense of touch similar to that of humans ever be developed in robots? Results on the physics of friction for fingerprint-like ridges sliding across textured surfaces may lead the way to tactile robotic sensors.

  • To understand and predict friction, it is crucial to observe sliding at the nanoscale to uncover the mechanisms at play. Here, the authors show that nano-contacts exhibit strength near the ideal limit, and find that pull-off forces predicted by continuum models are reduced by shearing.
