We present here a design of a unit cell of a mechanical metamaterial based on the use of a tensegrity structural configuration with metal rubber. Tensegrity combines the use of compression and tension-only elements, and allows the creation of structures with high rigidity per unit mass. Metal rubber is a multiscale porous metal material with high energy absorption and vibration damping capabilities under compressive load. The combination of the two structural and material concepts gives rise todoi:10.1063/1.5040850 fatcat:oyr3flnrfzagrondm46z4ii7gq
