At present, the widely used mechanical metamaterial has excellent characteristics such as negative thermal expansion, and high strength and high stiffness at low weight  However, once this mechanical metamaterial is constructed, its properties cannot be changed or adjusted  Recently, researchers have developed a new type of material which overcome this problem
History has proved that every breakthrough in new technologies and new materials will quickly cause drastic changes in related application fields.
 It is certain that in the near future, robots, smart wearable equipment and other fields will definitely fundamentally change
