Fig. 3: Characterization and properties of the M-SPDMS-A.

a Lateral image of the M-SPDMS-A. The black coating is the magnetic layer. b Cross-sectional image of the M-SPDMS-A. The inset cartoon shows the orientation of the magnetic coating. c SEM image of the cross section of the sample in (b). The width of the magnetic layer is ca. 23 µm, and that of the inner PDMS layer is ca. 80 µm. d Magnetic deformation of the M-SPDMS-A versus the thickness of the magnetic coating (y) and the inner PDMS layer (x), as indicated in (c). It is difficult to deform the M-SPDMS-A magnetically when y is larger than 110 μm (the right part), while it can be deformed when y is less than 110 μm (the left part). The inset shows photographs of M-SPDMS-A responding to a magnetic field in different cases.
