Mechanically Robust Flexible Metal Conductors by the Integration of Multilayer Graphene

Dr. Nam from the University of IL has developed flexible metal conductor that incorporates an interfacial layer of graphene. Adding a layer of graphene to the metal conductor enhances the failure strain of the electrode by 300% or more. This invention enhances the mechanical robustness and prevents abrupt electrical performance failure at large strains. Additionally, this invention allows for predictive failure for electrical devices based on measured electrical resistance. The invention has potential applications in flexible electronics. The invention also has potential application in predicative failure for electrical cables.
