Fig. 1: Schematics of dynamic transformation of magneto-elastomers.

The elastomer matrix exhibits reversible deswelling and expansion properties by adding solvent 1 and 2. With geometric constraints and absorption of solvent 2, the elastomeric structure could generate buckling transformation providing a template-free manner for the formation of 3D continuous heterogeneous magnetization. Diverse transformation of elastomeric structures could be achieved by using programmed magnetic inputs.
