A highly stretchable metal electrode is developed via the solution-processing of very long (>100 μm) metallic nanowires and a subsequent percolation network formation via low-temperature nanowelding. On page 3326, S. S. Lee, S. H. Ko and co-workers demonstrate the electrode's high electrical conductivity (∼9 ohm sq−1) and mechanical compliance (strain > 460%). This method is expected to overcome the performance limitations of current stretchable electronics such as graphene, carbon nanotubes, and buckled nanoribbons.
