Fig. 4: Various reconfigurable 3D microstructures based on non-volatile shape morphing.
a Design scheme, SEM images, and simulations of Cr/VO2 bimorph with different width and arrangement of Cr ribbons. Oblique lines in precursors refer to the bonding position with the substrate. The scale bar is 50 μm. b Design scheme, SEM images, and simulations of Cr/VO2 bimorph with reprogrammable creases. The first two rows are the design of single-arm with different Cr ribbons tuning bistable states. The third and fourth rows are symmetric and asymmetric four-arm grabbing actuators. Yellow circles in precursors refer to the bonding position with the substrate. The scale bar is 40 μm.
