Dielectric elastomers (DEs) can demonstrate fast and large in-plane expansion/contraction due to electric field (e-field)-induced Maxwell stress. For robotic applications, it is often necessary that the actuation converted into out-of-plane motions with mechanical frames. Despite their performance appeal, high driving e-field (20-100 V µm-1 ) demands bulky power accessories severely compromises durability. Here, a dielectric polymer be programmed diverse actuated under low (2-10 reported. The material crystalline dynamic covalent network reconfigured arbitrary 3D geometries. This gives rise geometric effect markedly amplifies actuation, leading designable when heated above its melting temperature become DE. Additionally, crystallization transition enables multimodal active deployability. These attributes result in unique design versatility for soft robots.
