  • Polymer locally comprising conductive areas
    Patent number: 9281103
    Abstract: A method for producing a conductive area in a polymer material comprises: providing a polymer layer comprising conductive particles with a density such that the polymer layer is insulating, heating the polymer material to a temperature higher than or equal to the glass transition temperature of the polymer material, compressing a portion of the polymer layer using a stamp, in order to obtain a density of conductive particles such that the portion becomes conductive, and removing the stamp from the polymer layer.
