Hydrogel actuators displaying programmable shape transformations promise to be core components in future biomedical and soft robotic devices. However, current hydrogel have shortcomings, including poor mechanical properties, slow response, lack of reprogrammability, which limit their practical applications . Existing molecular designs offer limited efficiency synergistically addressing these issues a single system. Herein, we propose strategy develop with muscle-mimetic aligned microfibrillar morphology, combining thermoinduced microphase separation alignment. The key our design is the introduction metal–phenolic complexes, not only induce irreversible sol–gel transition via concentrated coordinate ions above lower critical solution temperature (LCST) but also fix alignment bundle network due dynamic rearrangement. Our concept observed simultaneously achieve excellent properties (tensile strength ≈ 1.27 MPa, toughness 2.0 MJ m–3) ultrafast actuation (40.1% thermal contraction as short 1 s), long-lasting challenge field. In addition, hydrogels can reprogrammed into spiral, helical, biomimetic actuators. This work opens new opportunities realize real-world for smart machines by fundamentally breaking property limit.
