Abstract

Supercoiled Superelastic Metallic Metamaterials All-metallic supercoiled metamaterials achieve over 50% recoverable strain, triple buckling strength, and quadruple energy density over prismatic lattices. They enable advanced energy absorption, protective structures and vibration mitigation. The chiral quasi-zero-stiffness isolator sustains ultralow resonant frequencies (≤2 Hz) while supporting 100–1000× higher loads than existing schemes, also surpasses traditional springs' theoretical limits.
