Hydrogel　actuators　with　controllable　deformation　and　excellent　biocompatibility　are　widely　used　in　soft　robot,　valve,　drug　delivery　and　lenses.　However,　the　stimulation　response　performance　of　existing　hydrogel　actuators　mostly　focuses　on　a　single　active　layer,　which　greatly　affects　its　driving　performance　and　service　life.　In　this　work,　we　integrate　temperature-responsive　hydrogel　(Poly　(N-isopropyl　acrylamide),　PNIPAM)　and　pH-responsive　hydrogel　(polyacrylic　acid,　PAAc)　into　one　system　to　fabricate　a　dual　active　layer　composite　hydrogel　actuator　with　high　performance.　Based　on　the　PAAc　hydrogels　achieving　contract　or　expand　at　different　pH　values,　the　obtained　actuator　exhibits　admirable　bidirectional　bending　characteristics.　In　addition,　the　anisotropic　bamboo　sheet　endows　the　hydrogel　actuator　with　programmable　3　D　complex　deformation.　Benefitting　from　the　synergy　and　different　responsiveness　between　the　two　active　layers,　the　hydrogel　actuator　not　only　has　multiple　response　performance,　but　also　greatly　improves　its　deformation　degree　and　response　speed.　More　importantly,　these　promising　properties　of　the　actuator　have　broad　application　prospects　in　the　development　of　pattern　design　and　intelligent　switch.　This　work　proposes　a　promising　strategy　for　the　structural　design　of　hydrogel　actuators　with　excellent　performance,　and　encourages　more　exploration　of　the　application　range　of　the　actuator.　©　2023
