AN ECPR MASTER ELECTRODE AND A METHOD FOR PROVIDING SUCH ECPR MASTER ELECTRODE

摘要

An ECPR master electrode(10) and a method for providing such master electrode is provided. The master electrode comprises a carrier element (20) having an electrically conducting electrode surface(23) on a backside (21) and a topographical pattern (30) with an at least partly electrically insulating top (32) on a frontside (22) of said carrier element (20), said topographical pattern (30) is forming at least one electrochemical cell (34) in said carrier element, said electrochemical cell comprising a bottom (36) and at least one side wall (38), said bottom having an electrically conducting surface (40) being conductively connected to the electrically conducting electrode surface (23) on the back side (21) through the carrier element (20), wherein said at least one side wall (38) in said carrier element (20) is at least partly covered by an electrically insulating layer (42).
