Fabrication and magnetic actuation behaviors of MRS. a) Illustration of the fabrication process of MRS. b) Images of the prestretched MRS. w and s are the width and the interval of microblades, respectively. d is the diameter of the cord. c) Schematic illustration of MRS rotation under magnetic actuation. α and β are the rotation angles of MRS and actuating magnetic field, respectively. θ is the tilt angle of MRS. d) Magnetic hysteresis loop of MRS. Insert is the magnetization profile of MRS. e) Images and FEA results of the swing and rotation process of MRS under magnetic actuation. f) The maximum rotation cycles of MRS with d of 0.07, 0.14, 0.20, 0.35, 0.47, and 0.68 mm under 60 mT magnetic actuation. g) The maximum rotation cycles of MRS with d of 0.14 mm under actuating field intensity of 25, 60, 105, and 130 mT.
