Programmable 3D Morphing Bionic Gradient Hydrogel Actuators with Fast Response and Large‐Amplitude Deformations

deformation behavior are realized. Inspired by inchworms and springtails, the hydrogels are pre-programmed to harness its fast-response and large-amplitude deformation, enabling light-driven soft robots to achieve biomimetic actuation, including tumbling, jumping, and crawling. This programmable, fast-response, 3D shape-morphing gradient hydrogel actuator expands the possibilities for applications in complex dynamic systems, including soft robotics and bionic devices.
