Delocalized Deformation Enhanced Reusable Energy Absorption Metamaterials Based on Bistable Tensegrity (Adv. Funct. Mater. 5/2025)

Abstract

Mechanical Metamaterials

In article number 2410217, Zhigang Wu, Fei Pan, Jianing Wu, and co-workers propose a tensegrity-based assembly strategy to construct the developed novel bistable tensegrity structures into mechanical metamaterials with a delocalized deformation mechanism. The metamaterials achieve an energy-absorbing capacity of 26.4 kJ (kg m²)⁻¹ over 10 000 cycles, outperforming other reusable materials by 2 orders of magnitude in energy-absorbing capacity and reusability, respectively.
