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

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.
