SENSOR ELEMENT FOR DETECTING AN ANALYTE IN A BODY FLUID

A sensor element (110) for determining the concentration of at least one analyte in a body fluid (124) is disclosed. The sensor element (110) is at least partially implantable into a body tissue. The sensor element (110) has a substrate (112) and at least two electrodes (114, 116), the electrodes (114, 116) comprising at least one working electrode (114) and at least one counter electrode (116). The working electrode (114) comprises at least one conductive pad (118) applied to the substrate (112), wherein at least one electrically conductive sensor material (120) is applied to the conductive pad (118). The electrically conductive sensor material (120) comprises at least one detector substance (122) adapted to perform an electrically detectable electrochemical detection reaction with the analyte. The counter electrode (116) comprises at least one counter electrode conductive pad (126) applied to the substrate (112). The sensor element (110) further comprises at least one electrically insulating material (130). The electrically insulating material (130) surrounds the counter electrode (116) on all sides. A height of the electrically insulating material (130) at least equals the height of the counter electrode conductive pad (126).
