Morphable 3D mesostructures constructed by incorporating twisting into a loading-path controlled scheme for mechanical assembly on kirigami substrates. (A) Temporal sequence of changes in applied strains for 2 different loading paths. (B) Undeformed and deformed configurations of an elastomeric substrate with rectangular units (aspect ratio = 2.5) at different positions (corresponding to the positions in A) along the loading paths. (C) Two-dimensional geometries, FEA predictions, and experimental images (optical) of 3 morphable 3D mesostructures that result from different loading paths on kirigami substrates. (Scale bars, 1 mm.)
