"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.

“The dirty little secret of the satellite industry is we’ve got all these amazing sensors up there that produce terabytes, or even petabytes, of data every few minutes, and they throw most of it out because they can’t do the computing on board and they can’t get round trip back and forth to the surface fast enough,” DeMillo told TechCrunch.
