Folded and cut thin structures offer innovative solutions for fluid interaction and actuation. Perforated sheets in flow deform asymmetrically, driven by the interplay of fluid forces and mesostructure geometry. Origami-inspired patterns, like the watebomb base, enable passive drag reduction and adaptive reconfiguration. Folded ribbons enhance snap-through dynamics, releasing more energy and achieving faster motion than flat strips. These findings open pathways for applications in flow-responsive devices, drag control, and soft robotics.
