Mechanical Metamaterials: Dome‐Patterned Metamaterial Sheets (Adv. Sci. 22/2020)

In article number 2001955, André R. Studart, Andres F. Arrieta, and co‐workers demonstrate a family of mechanical metamaterials exploiting sheets patterned with locally bistable domes. The metamaterial's strong hierarchical response enables tunable mechanical properties and programmed geometry adaptation. The strain energy stored by local dome inversion simplifies soft robotics grippers' actuation and enables memory and computation of spatially‐distributed mechanical signals in thin skins.
