Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks

Advanced Materials, EarlyView.
Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.
