Multifunctional Mechanical Metamaterials
The accordion can deliver a diverse range of melodies contingent upon the sequence of keys and bellows movement activated by the performer. In article number 2301109, Lei Wu and Damiano Pasini introduce a multifunctional mechanical metamaterial whose building block resembles the individual keys and bellows of an accordion. By activating the high‐energy stable...
Snap‐through instability has been widely leveraged in metamaterials to attain non‐monotonic responses for a specific subset of applications where conventional monotonic materials fail to perform. In the remaining more plentiful set of ordinary applications, snap‐through instability is harmful, and current snapping metamaterials become inadequate because their capacity to snap cannot be suppressed...
