Metallic nanostructures such as nanowires and nanosheets are promising candidates for the fabrication of highly conductive electrodes, but the practical application of metal nanostructure-based electrodes in stretchable electronics is often limited by significant performance degradation associated with poor mechanical stability of a nanowire or nanosheet percolation network against repeated deformation. We studied failure behaviors of stretchable electrodes made of Ag nanowires or Au nanosheets deposited on various elastomeric substrates such as PDMS and Ecoflex during stretching cycles, and suggested a way of improving stretchability and stability of these metal nanostructure-based stretchable electrodes.
