Abstract: Some highly stretchable kirigami metallic glass (MG) structures with ultra-small strain energy loss during cyclic loading are developed. Less than 3% of strain energy loss is achieved after 1000 loading/unloading cycles, which is much smaller than the Kapton or nanocomposites-based kirigami structures. By optimizing the kirigami pattern design and smoothing the kirigami cuts may further reduce the stress energy loss, and one kirigami MG structure even shows no obvious strain energy loss. They are potentially useful for developing reversible mechanical metamaterials/devices or substrates of functional optoelectronic devices.
