Hyperelastic Starch Hydrogel Configures Edible and Biodegradable All‐Components for Soft Robots

open access: yesAdvanced Science, EarlyView.
Hyperelastic starch hydrogel is tailored via a phase separation strategy of solvent‐antisolvent co‐modulation. The mechanical performance of starch hydrogel is widely tuned with maximum strains: 194.4–361.4%; maximum tensile stresses: 34–192 kPa; and Young's moduli: 36.0–205.8 kPa. Notably, the hydrogel achieves complete soil degradation within 24 days

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

open access: yesAdvanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...
