1. An electrode for detecting a bioelectrical signal on a skin surface,
said electrode comprising
a skin contact part,
a substrate made of a metal,
a coating comprising iridium oxide,
wherein the coating covers at least part of the skin contact part of the electrode,
wherein the coating comprises a nanostructured surface pattern, and
wherein the nanostructured surface pattern is configured with multiple intersecting ridges to provide a capillary effect, making the part of the skin contact part that is covered by the coating hydrophilic when in contact with the skin surface.
