The metamaterial on the left offers multiple functionalities by changing its deformation. By compressing it slowly (bottom right) or fast (top right), we can change whether the metamaterial shrinks or expands when compressed.
The metamaterial on the left offers multiple functionalities by changing its deformation. By compressing it slowly ( bottom right ) or fast ( top right ), we can change whether the metamaterial shrinks or expands when compressed. In recent years, the popularity of metamaterials has increased significantly. These materials are not found in nature or made using chemical reactions, but are designed geometrically in the physics lab. Metamaterials can be given special, often counterintuitive, properties. For the first time, physicists have now developed a toolbox to create materials that feature multiple such properties simultaneously. The research was published in the Proceedings of the National Academy of Sciences this week.
