Collapsible structures may be formed from planar solids. The structures may be comprised of multiple planar objects hingedly connected, where each planar object may include magnetic materials (e.g., magnets, ferromagnetic metals) or electromagnetic materials. Using the magnetic or electromagnetic materials, the connected planar objects may be arranged as a single planar object with multiple layers, or may be arranged as a three-dimensional (3-D) object, where the magnetic or electromagnetic materials may be used to retain the formed 3-D object shape. Application of a current to the electromagnetic materials may cause the collapsible structure to form the 3-D object, and removal of the electric current may cause the collapsible structure to revert to a single planar object. Multiple structures may be combined to form larger structures. |

1. A six-sided pentagonal structure comprising:
a first subgroup including a first, second, and third substantially pentagonal structure, the first, second, and third substantially pentagonal structures arranged to share a first common edge and at least a first common vertex with approximately one hundred and twenty degrees between adjacent substantially pentagonal structures; and a second subgroup including a fourth, fifth, and sixth substantially pentagonal structures, the fourth, fifth, and sixth substantially pentagonal structures arranged to share a second common vertex and a second, third, and fourth common edge with adjacent substantially pentagonal structures in the second subgroup; wherein the first and second subgroups are arranged such that the first common vertex is collocated with the second common vertex, and the first subgroup first, second, and third substantially pentagonal structures is arranged to share an edge with the second subgroup second, third, and fourth common edges, respectively. |
