The present disclosure relates to a body electrode (14) comprising a body-facing layer (22), a conductive layer (24) and a conductive body (26). The conductive layer (24) comprises a first material composition and the conductive body (26) comprises a second material composition. The second material composition has a lower electrical resistance than the first material composition. The conductive body (26) is located within and/or on the conductive layer (24). The body electrode (14) comprises a plurality of fluid transport passages (30) extending through both of the body-facing layer (22) and the conductive layer (24).
