Self-locking degree-4 vertex origami structures [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 A generic degree-4 vertex (4-vertex) origami possesses one continuous degree-of-freedom for rigid folding, and this folding process can be stopped when two of its facets bind together. Such facet-binding will induceself-lockingso that the overall structure stays at a pre-specified configuration without additional locking elements or actuators.

Self-locking and stiffening deployable tubular structures [PDF]
Proceedings of the National Academy of SciencesDeployable tubular structures, designed for functional expansion, serve a wide range of applications, from flexible pipes to stiff structural elements. These structures, which transform from compact states, are crucial for creating adaptive solutions across engineering and scientific fields.

Self-locking Kirigami surfaces via controlled stretching
Communications Engineering, 2023 Abstract Kirigami provides a powerful strategy to transform two-dimensional elements into complex three-dimensional functional structures with lengths ranging from nanoscale to microscale and macroscale. The stability and programmability of forming three-dimensional structures through mechanical actuation, whether external or self ...
