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
The stability of this new material's response to the magnetic field and its requirements for the intensity of the magnetic field are still being repeatedly detected and tested.
 It is certain that in the near future, robots, smart wearable equipment and other fields will definitely fundamentally change
