Shape Deformable Hydrogels

Imagine what functions can be performed with a soft, flexible but tough transformer that can change its shape upon external stimuli? Hydrogels are three-dimensionally cross-linked polymeric networks that can absorb a large amount of water while maintaining their solid-like shapes. They are typically soft and wet materials. Some smart hydrogels can change their geometric shapes
