Abstract

The elastic performance of kirigami metallic glasses (MGs) plays a key role for their applications as potential mechanical metamaterials, however, the mechanisms on how to achieve programmable large elasticity in these kirigami MGs are still unknown. In this work, kirigami MGs, with programmable stretchability reaching 317%, were fabricated, demonstrating super elasticity larger than 277%. The high stretchability and super-elasticity are mainly attributed to the elastic out-of-plane bending of the kirigami elements rather than rigid deformation. The super elastic kirigami MGs can be developed for use as high stretchable mechanical/functional metamaterials/devices, such as wearable sensors and stretchable electronics.
