Mechanical coupling is an engineering phenomenon in which different deformation modes of a structure are not independent; loading in one mode induces deformation in others. For example, even when a structure is subjected only to tensile loading, it may undergo not only axial extension but also shear, bending, or twisting simultaneously. This coupling effect, where multiple deformation modes occur concurrently, enables the utilization of diverse mechanical responses and is therefore attractive for various engineering applications, including robotic arms, mechanical computing systems, cantilever beams, and helicopter blades. However, many previously proposed materials and structures suffer from fabrication complexity and limited allowable deformation ranges. To overcome these limitations, this study introduces kirigami-based structures that enable flexible and programmable mechanical motions.
