内容简介：

Soft robots and smart structures driven by stimuli-responsive materials have unique advantages over conventional rigid robots, especially in their high adaptability for field exploration and seamless interaction with humans. Investigating the mechanics with multi-field coupling effects of dielectric elastomers and responsive hydrogels, we are able to harnessing the instabilities and large deformations, enhancing the performances of soft smart structures. For a soft robot with practical applications, the grand challenge lies in achieving self-powered soft robots with high mobility, environmental tolerance, and long endurance. We have designed a soft electronic fish with a fully integrated onboard system for power and remote control. Without any motor, the fish is driven solely by a soft electroactive structure made of dielectric elastomer and ionically conductive hydrogel. The electronic fish can swim at a speed of 6.4 cm/s (0.69 body length per second), which is much faster than previously reported untethered soft robotic fish driven by soft responsive materials. The design principle can be potentially extended to a variety of flexible devices and soft robots.
