Abstract
An auxetic metamaterial including a plurality of interconnected building blocks that are deformable between a collapsed position and an expanded position upon the application of a load. The building blocks are bistable, and define a stable state in both the collapsed position and the expanded position. In the stable state, the building blocks maintain the collapsed position or the expanded position, even after removal of the load applied on the building block.
