We report a microplasma-based process to fabricate stretchable, electrically conductive metal patterns from metal-cation containing polymers. The technique is compatible with prestraining strategies, allowing films to remain conductive with almost no drop in resistance up to 35% strain. We show that the stretchability of the films is related to uniform strain delocalization which is made possible by how the metallized layer is formed in situ, growing from within the polymer matrix rather than by deposition, to create a quasi-monolithic structure without a well-defined metal-polymer interfacial boundary.
