At small scales, shape-programmable magnetic materials and self-sensing conductive have an enticing potential for realizing the functionalities that are unattainable by traditional machines. This work reports a facile preparation method of aself-sensing magnetism-responsive anisotropic films (SMAF) in which can be predesigned, oriented, patterned without requiring external field generator or other expensive devices. A variety shaped magnetoactive with complex chain-orientation structures achieve advanced actuation functions been developed, such as magnetically driven flowers, windmills, leaves. It is also verified as-prepared samples coated sensing layer distinguish different modes, inward bending, outward twisting, combined deformation, would conducive to further exploration development directionally responsive applications smart actuating system soft robotics.
