N2 - The present invention relates to a method of manufacturing an elastic conductor an elastic conductor obtainable by the method and an electronic device, in particular a wearable and/or stretchable electronic device, comprising the flexible conductor. The method of manufacturing an elastic conductor comprises the steps of: (a) forming a solid metal layer on a surface of an elastomer substrate; (b) optionally, activating a surface of the solid metal layer by removing a passivation layer from the surface of the solid metal layer; (c) applying a liquid metal onto an exposed surface of the solid metal layer; (d) forming an alloy from the solid metal layer and the liquid metal such that the alloy comprises at least one element originating from the solid metal layer and at least one element originating from the liquid metal, such that the alloy is composed of at least 5 wt.-% of material originating from the solid metal layer and at least 15 wt.-% of material originating from the liquid metal; (e) removing un-alloyed liquid metal from a surface of the alloy formed in step (d); (f) optionally, applying a protective elastomeric film.
