The present invention relates to a method for producing an implantable multielectrode array (1), comprising the steps of: providing a substrate (2) on which a plurality of conductors (10) are arranged, wherein each conductor (10) comprises a section (100) comprising a constriction (101), and wherein said sections (100) extend parallel to one another in a first direction (D1); removing a portion of the substrate (2) such that a first and a separate second substrate part (21, 22) is formed, which substrate parts (21, 22) are separated by a gap (20), and wherein each section (100) extends in the first direction (D1) from the first substrate part (2a) across the gap (20) to the second substrate part (2b), and exerting a first force (F1) on the first substrate part (2a) and a second force (F2) on the second substrate part (2b) and heating said sections (100), such that a fracture (102) of the respective section is generated at the respective constriction (101), which fracture (102) separates the respective section (100) into an electrode (3) protruding from the first substrate part (2a) and an electrode (3) protruding from the second substrate part (2b). Furthermore, the present invention relates to an implantable multielectrode array (1) as well as to a device (1) for manufacturing an implantable multielectrode array (1).
