title: A Bioinspired Swimming and Walking Hydrogel Driven by Light-Controlled Local Density.
abstract: A hydrogel exhibits a real-time depth-controllable swimming motionvia light-mediated modulation of local density to mimic the volume changes found in the bladders of fish. Moreover, other motions, e.g., rolling, somersaulting, and bipedal-like walking, can also be realized by designing or combining gel shapes, and the location of light.
