a Depicts models of dried Sphagnum characterized by a porous surface facilitating efficient water absorption and storage. b Illustrates the schematic of a hydrophilic hydrogel, showcasing its absorption-induced expansion properties. c Presents a schematic representation of a hydrophobic elastomer immersed in water, maintaining its original state. d Demonstrates the absorption-induced expansion behavior of a porous hydrophobic elastomer after immersion in water. e Displays schematics of two composite systems: one combining porous elastomer with pure elastomers for programmable self-shaping transformations, and the other combining porous elastomers with magnetic elastomers for the preparation of magnetically driven robots.
