Fig. 4: Magnetic composites induce jamming selectively along specific directions within a multi-dimensional structure.

a 3-by-3 two-dimensional structure in the x-y plane can be jammed only in x, only in y, and in both x and y, based on the direction of the applied magnetic field (H). b A lifting experiment demonstrates how a three-dimensional structure can be jammed in all possible combinations of the three dimensions (none, x, y, z, xy, xz, yz, xyz). c Magnetic composites also enable multi-dimensional stiffness-tunability.
