  • Curved origami-based metamaterials for in situ stiffness manipulation
    Patent number: 11964384
    Abstract: A curved origami-based metamaterial includes a panel of material having a plurality of curved creases each disposed within a plane of the panel. The panel is configured to be folded along one of the plurality of creases, and the panel is also configured to be bent about an axis disposed outside the plane of the panel. Stiffness manipulation is configured to be achieved in situ by activating a different one of the plurality of curved creases.

  • Origami-based collapsible and watertight cases
    Patent number: 11267613
    Abstract: A foldable, waterproof case includes a first wall and a second wall coupled to the first wall. The first and second walls at least partially define a cavity within the case. A lid is coupled to the second wall and is configured to selectively cover the cavity. A hinge is disposed between the first wall and the second wall. The first wall is rotatable relative to the second wall between a first, expanded position of the case and a second, collapsed position of the case. In the first position, the cavity includes a first volume and in the second position, the cavity includes a second volume that is less than the first volume. The hinge provides a waterproof connection between the first and second walls in the first position and in the second position.
