Programmable 3D Self‐Folding Structures with Strain Engineering

Self‐assembly of three‐dimensional (3D) structures, through bending, twisting, folding, and buckling, has garnered broad interest among physicists, mathematicians, chemists, and biologists. Herein strain engineering and geometric frustration as an on‐demand strategy for fabricating spontaneous rolling “origami” structures with programmable multistability across multiple length scales are exploited. Through experiments, theory, and finite element...
