NOVELTY - The electrode has a chitosan layer i.e. resorbable carrier substance, and graphene oxide layer i.e. insulator, formed by a conductive graphene layer i.e. core. The conductive graphene layer conducts nerve signals by a laser. A water-insoluble layer is arranged between the chitosan layer and the graphene oxide layer. An electrical insulating layer is formed around the graphene oxide layer, where the electrode is arranged with the conductive graphene layer. USE - Flexible and resorbable electrode for brain. ADVANTAGE - The electrode increases penetration strength of brain tissue and rigidity of the chitosan layer and improves manufacturing process of the graphene oxide layer.
