Key Points

  • This research aims to develop supercoiled superelastic metallic metamaterials to enhance energy density and vibration mitigation capabilities.
  • Designed all-metallic supercoiled metamaterials with advanced structural properties.
  • Tested performance metrics such as recoverable strain, buckling strength, and energy density compared to prismatic lattices.
  • Evaluated chiral quasi-zero-stiffness isolator's load-bearing capabilities and resonant frequencies.
  • Achieved over 50% recoverable strain and triple the buckling strength of conventional designs.
  • Observed quadruple energy density compared to prismatic lattices.
  • The chiral isolator supported loads 100-1000 times greater than existing solutions, resonating at ultralow frequencies of ≤2 Hz.

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. More details can be found in the Research Article by Xin Fang, Weiqiu Chen, Huajian Gao, and co-workers (DOI: 10.1002/adma.202517334).
