Realization of self-propelled multimodal locomotions. a Schematic representation and snapshots of a self-rolling motion of TMES at α = 90° on a hot surface at 70 °C. b Schematic illustration of self-rotation movement with direction determined by the alignment angle of PVDF in TMES, and snapshots of TMES at α = 45° during an anticlockwise rotation process. c Time-dependent rotation angle of TMES at four different alignment angles during three consecutive 360-degree rotation cycles. d The locomotion modes of TMES strips at different alignment angles on the hot surface with temperatures ranging from 50 to 75 °C
