WebFlexible metamaterials have been increasingly harnessed to create functionality through their tunable and unconventional response. Herein, chiral unit cells based on Archimedean spirals are employed to transform a linear displacement into twisting. First, the effect of geometry on such extension-twisting coupling is investigated.

If the chiral metamaterials become anisotropic, such as the two-fold (C 2) rotational symmetry, the polarization conversion between the two spin states in reflection would appear. It is important to note that two-dimensional (2D) planar ... WebAuxetic mechanical metamaterials (AAMs) exhibit extraordinary negative Poisson's ratio (NPR) properties because of their unique cellular auxetic geometric configurations. According to their geometric designs, typical AAMs can be divided into several types, such as re-entrants [1], honeycomb [[2], [3], [4]], chiral [5, 6], lozenge, and origami ...
