An ecpr master electrode, and a method for providing such master electrode

摘要

A method for providing an ECPR master electrode is hereby presented. The method comprises the steps of providing a circular carrier element (101) having an electrically conducting electrode surface (106) on a back side (104)and a topographical pattern (107) with an at least partly electrically insulating top on a front side of said carrier element, said topographical pattern comprising a plurality of electrochemical cells (109) in said carrier element, each one of said electrochemical cells comprising a bottom (111) and at least one side wall (112), said bottom having an electrically conducting surface being conductively connected to the electrically conducting electrode surface on the back side through the carrier element, wherein the step of providing said topographical pattern comprises distributing said topographical pattern across a device area (130) extending radially from the centre of the carrier element towards the periphery of said carrier element, and passivating a peripheral part of said device area by arranging an electrically insulating layer on top of said peripheral part (140) of said device area.
