Recently, researchers have invented a new material with super elasticity. This material can be stretched from 1 inch to more than 100 inches. At the same time, this material can repair itself and can be controlled by voltage. 
If the general material is damaged, it needs to be restored by solvent repair or thermal repair, and the material can recover by itself at room temperature.
 the researchers believe that the use of the material can be made into artificial muscles to replace human muscles, so as to bring good news to patients who cannot recover their functions after muscle damage.
