Metamaterials are a very special type of man-made material. Its function is determined by its structure rather than its composition, and it can change the properties of objects, such as bending intangible light and sound, or bending soft objects. Objects can become rigid and even suppress seismic waves during earthquakes. However, each function requires a special mechanical structure, making metamaterials only used for specific purposes and not widely used.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering at Harvard University have developed a device that can be used The general framework for designing metamaterials can be changed according to size. That is to say, it can be applied to everything from buildings to nanoscale photonic crystals, waveguides, and metamaterials.

Sounds mysterious, right? Simply put, researchers have developed a polyhedral structure that looks a lot like a 3D paper puzzle and can change depending on the task function required.For researchers, the versatile properties of "paper puzzles" can be used in a variety of situations, thus greatly expanding the application scope of metamaterials.
But for us ordinary people, the logic behind these metamaterials is left to these experts to study. We just need to sit in front of the computer and appreciate the ever-changing "paper puzzle". The constantly deforming metamaterials are simply like The magic and dazzling visual effects will attract everyone to keep watching, because you will never know what the puzzle in your hand will look like in the next second!
