Dual-chirality flexagon linkages with infinite eversion and surface reconfigurability

Proceedings of the National Academy of Sciences, Volume 123, Issue 25, June 2026.
SignificanceFlexagon-based kirigami enables surface reconfigurability and eversion; however, unexplored kinematic mechanisms and inherent material constraints have limited its applications. We introduce a class of dual-chirality flexagon linkages that …
