A thin film for a lead for brain applications includes at least one section comprising a high conductive metal and a low conductive metal, whereby the low conductive metal is a biocompatible metal and has a lower electrical conductivity than the high conductive metal and whereby the high conductive metal is at least partially encapsulated by the low conductive metal. Furthermore, the present invention relates to a method of manufacturing a thin film for a lead for brain applications and a deep brain stimulation system.
