When a kirigami sheet (a sheet with cut patterns) is placed in flow, it can direct the flow in desired orientations, depending on the cut patterns. In the deployed parallel cut kirigami sheet shown here, a transition from jets to vortex shedding is observed in the wake of the kirigami sheet as the openings widen (above image). By systematically changing the gap sizes, we observe this transition from jets (lower right) to vortex shedding (lower left) in the wake of uniformly-cut rigid sheets as well.
