Abstract Poly(N-isopropylacrylamide)-based stimuli-responsive hydrogel actuators have made significant progress. By introducing responsive modules such as photothermal nanoparticles, the can respond to environmental changes and construct anisotropic structures, allowing quickly bend realize complex shape deformation. However, there remains a need enhance mechanical properties of these hydrogels accommodate multiple deformation actions different application scenarios, compatibility between nanoparticles improve comprehensive performance materials are still issues that be solved. In this study, we modified two-dimensional MXene nanosheets with polydopamine (PDA) obtain P-MXene, which served agent stably dispersed within system. We copolymerized thermosensitive N-isopropylacrylamide (NIPAm) 2-(dimethylamino)ethyl methacrylate (DMAEMA) in situ used direct current electric field induce concentration gradient distribution P-MXene hydrogel, resulting preparation good stretchability conductivity.

Abstract Biological structures exhibit autonomous and intelligent behaviors, such as movement, perception, responses to environmental changes, through dynamic interactions with their surroundings. Inspired by natural organisms, future soft robots are also advancing toward autonomy, sustainability, interactivity. This review summarizes the latest achievements in untethered based on 1D 2D nanomaterials. First, performance of actuators designed different is compared. Then, development basic locomotion forms, including crawling, jumping, swimming, rolling, gripping, multimodal, mimicking biological motion mechanisms under stimuli, discussed. Subsequently, various self‐sustained movements imbalance static stimuli introduced, light tracking, self‐oscillating, self‐crawling, self‐rolling, flying. Following that, progress integrated additional functionalities sensing, energy harvesting, storage summarized. Finally, challenges faced this field prospects for
