New metamaterial stores 160x more energy, paving the way for smarter robots

A breakthrough in mechanical metamaterials from Karlsruhe Institute of Technology could revolutionize energy storage and robotics. The new material, made of twisted rods in a specific pattern, stores up to 160 times more elastic energy than existing materials while maintaining strength and flexibility. This innovation could enhance robots, machines, and flexible structures, with potential applications in robotic limbs, energy-efficient machinery, and elastic joints for exoskeletons. The material can absorb and release significant energy without permanent deformation.
