The fabrication process of METMs and its actuation under static and alternating magnetic fields.

Caption

The 2D PET precursor is defined by femtosecond laser and the discrete magnetization profiles are patterned by UV curing of magnetic composite materials. The 2D precursor is then attached to a pre-stretched elastomer and assembled into 3D mesostructure after stress release. Under a static magnetic field, the METM demonstrates high-order deformation. Under a rotating magnetic field, the METM shows high-frequency actuation.
