A general strategy for fabricating a double layer self-deformed shape memory hydrogel which includes a thermo-responsive actuating layer and a pH-responsive memorizing layer is presented. Compared with traditional shape memory polymer systems, the temporary shape of the hydrogel could be generated by thermo-responsive actuating layer upon the trigger of heat without the need of external force, which could be further memorized by the pH-responsive memorizing layer.
