Large characteristic lengths in 3D chiral elastic metamaterials

Chiral mechanical metamaterials enable unusual effects, such as coupling between strain and twist. Here, manufactured microstructured samples with >105 chiral unit cells exhibit large characteristic lengths, in agreement with analytical and numerical modelling and micropolar continuum elasticity.
