Ultralight, ultrastiff mechanical metamaterials [PDF]
Microlattices make marvelous materials Framework or lattice structures can be remarkably strong despite their very low density. Using a very precise technique known as projection microstereolithography, Zheng et al. fabricated octet microlattices from polymers, metals, and ceramics.

3D Auxetic Metamaterials with Elastically‐Stable Continuous Phase Transition
In solid state physics, phase transitions can influence material functionality and alter their properties. In mechanical metamaterials, structural‐phase transitions can be achieved through instability or buckling of certain structural elements.

Transformable topological mechanical metamaterials [PDF]
AbstractMechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson’s ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways

Static non-reciprocity in mechanical metamaterials [PDF]
Reciprocity is a fundamental principle governing various physical systems, which ensures that the transfer function between any two points in space is identical, regardless of geometrical or material asymmetries.

Robust temporal pumping in a magneto-mechanical topological insulator
A robust time-controlled energy pumping in a classical metamaterial remains to be achieved. Here, Grinberg et al. demonstrate a temporal topological pump that produces on-demand, robust transport of mechanical energy using a one-dimensional magneto ...
