Abstract
Sensor elements are provided for determining at least one analyte concentration in a body fluid. The sensor elements are at least partially implantable into a body tissue and have a substrate and at least two electrodes. One electrode is a working electrode having at least one conductive pad applied to the substrate and at least one electrically conductive sensor material is applied to the conductive pad that includes at least one detector substance adapted to perform an electrically detectable electrochemical detection reaction with the analyte. Another electrode is a counter electrode having at least one counter electrode conductive pad applied to the substrate. The sensor elements also include at least one electrically insulating material that surrounds at least the counter electrode on all sides, where a height of the electrically insulating material at least equals a height of the counter electrode conductive pad.
