Introduction to directionally compliant metamaterials (DCMs). a A flexure system that exclusively achieves the desired rotational degree of freedom (DOF) of an elbow but fails to assume its shape and, b an aperiodic DCM that can be shaped to conform to any elbow shape while also achieving high stiffness in all directions except about, c, the desired compliant rotational DOF
