    "body_text": "The actuator varies material thickness across origami-like facets and creases so a compliant print bends in intended directions while resisting unwanted deformation. It needs one material, one print and no added reinforcement; linked modules mechanically program more complex trajectories. The authors demonstrate the same motion primitive in a four-axis wearable haptic device, a three-axis force-feedback joystick and an underwater gripper, establishing a fabrication approach rather than a production-ready product.",
