Nowadays, there’s really no difference between a Wi-Fi booster and Wi-Fi extender - they’re just different names for the same thing. Previously, however, Wi-Fi boosters were devices that received signals from wireless routers, broadcasting them to another network. This essentially extends the range of the signal. Wi-Fi extenders expand the coverage within your home’s Wi-Fi network, but often you will see extenders described as boosters.
"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.
