"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.
我国知识产权发展从无到有、由弱变强、由多向优，专利思维、版权意识、品牌文化深入人心，尊重知识、鼓励创新的社会氛围越来越浓。今天，从知识产权大国迈向知识产权强国，我国保护知识产权的决心更加坚定，创新创造的活力也必将进一步迸发。
