TL;DR: In this article, the design principles leading to these properties are identified and discussed, in particular, linear and mechanism-based metamaterials (such as origami-based and kirigami based metammaterials), harnessing instabilities and frustration, and topological and nonlinear metam materials.

TL;DR: This work presents an experimental and theoretical study of an active metamaterial—composed of coupled gyroscopes on a lattice—that breaks time-reversal symmetry and presents a mathematical model that explains how the edge mode chirality can be switched via controlled distortions of the underlying lattice.

TL;DR: In this article, it was shown that topological modes can exist that are robust against a range of structural deformations in metamaterials, and that these modes can be used to construct topological topologies.

TL;DR: This work shows that, for more general curved surfaces, curvature may be relaxed by pleats: uncharged lines of dislocations that vanish on the surface and play the same role as fabric pleats, and experimentally investigates crystal order on surfaces with spatially varying positive and negative curvature.

TL;DR: This work builds a topologically protected mechanism that can perform basic tasks such as transporting a mechanical state from one location to another and paves the way toward adopting the principle of topological robustness in the design of robots assembled from activated linkages as well as in the fabrication of complex molecular nanostructures.
