Abstract: A method for manufacturing a multilayer structure comprises depositing a coat of graphene ink on a passivation layer; bonding a polymer so-called carrier layer using an adhesive; drying the coat of ink; removing some of the graphene and the passivation layer from a first face without cutting into the polymer carrier layer and while removing the polymer carrier layer and the cut-out zones from the second face; bonding adhesive strips along the longitudinal periphery on each side of the passivation layer and in part of the zones with the cut-out graphene; placing electronic components, electrodes, on a polymer substrate layer; and bonding the passivation layer to the substrate layer with the electronic components in that part of the passivation zones that has the graphene cut out.
