DOI: 10.1002/adma.202209870
Abstract: Hydrogel actuators are important for designing stimuli‐sensitive soft robots. They generate mechanical motion by exploiting compartmentalized (de)swelling in response to a stimulus. However, classical switching methods, such as manually lowering or increasing the pH, cannot… read more here.
