Abstract Self‐sustained motions are widespread in biological systems by harvesting energy from surrounding environments, which inspire scientists to develop autonomous soft robots. However, most‐existing robots require dynamic heterogeneous stimuli or complex fabrication with different components.

Shape transformation, a key mechanism for organismal survival and adaptation, has gained importance in developing synthetic shape-shifting systems with diverse applications ranging from robotics to bioengineering. However, designing controlling microscale materials remains fundamental challenge various actuation modalities. As structures are scaled down the microscale, they often exhibit size-dependent characteristics, underlying physical mechanisms can be significantly affected or rendered ineffective. Additionally, surface forces such as van der Waals electrostatic become dominant at resulting stiction adhesion between small structures, making them fracture more difficult deform.
