Active Design of Chiral Cell Structures that Undergo Complex Deformation Under Uniaxial Loads

•Vector deformation, adjustable over a wide area under uniaxial loads, was controlled by the chiral cells’ geometric parameters. The chiral cells’ deformations were summed as vector additions.•Structures with various coupling deformation properties were designed, such as compression to dislocation and compression to bending.•A variable-geometry wing was designed.•Based on a genetic algorithm, an active design method was used to encode target deformations into the structures.
