Deploying kirigami under flow

Curvy-cut kirigami offers an efficient approach for designing deployable structures. Recent studies have explored a range of directions, from programmable complex 3D geometries to the investigation of kirigami–flow interactions, illustrated by elegant kirigami parachutes. Can a curvy-cut kirigami structure be designed to deploy into a prescribed target shape within a fluid flow? How does the drag force evolve as the structure deploys? The evolution of force distribution, along with the changing porosity caused by the opening of kirigami cuts, presents new challenges for systems operating in fluid environments.
