Abstract | The movements of soft-bodied animals have long inspired scientists to design soft actuators (1) that can convert various forms of energy into mechanical work. Hydrogels (2) hold the potential to close the performance gap between synthetic actuators and biological organisms because of their similarity to soft tissues, excellent biocompatibility, and large deformations. Expansion toward soft robots and artificial muscles challenges their status, calling for hydrogels with large actuation forces and fast responses to external stimuli. However, existing hydrogel actuators usually exhibit low actuation forces (≤2 N) and slow responses. On page 301 of this issue, Na et al. (3) report by-passing state-of-the-art hydrogel actuators to achieve an ultrahigh actuation force (730 N) and high speed by combining turgor design and electroosmosis. |
