Pneumatic Origami Joints
This research investigates the design and fabrication process of an adaptive joint using foldable 3D printed structures encased in heat-sealed synthetic polymer films (e.g. airtight plastic casing). The proposed joint can be pneumatically actuated using the airtight casing, and the shape of the deformation can be controlled using origami-inspired 3D printed structures. A zigzag microstructure is designed for the connection portion of the origami structure inside the joint, in order that the rigid 3D printed material (PLA) acquires properties of mollusk material, such as flexibility and softness. Finally, the paper presents some applications adopting pneumatic origami joints which can interact with people or adapting the indoor environment, and compares
the advantages of this pneumatic technology with mechanical technology.
