  • Publication number: 20240060927
    Abstract: An analyte sensor for determining at least one analyte and a method for producing an analyte sensor are disclosed. The analyte sensor has a substrate. A working electrode and a conductive layer are located on different sites on the substrate. A layer having silver and/or a silver compound partially covers the conductive layer. A protective layer covers (i) the layer having silver, and also covers (ii) a portion of the conductive layer. The disclosed analyte sensor significantly reduces noise during measurements. The method can be performed in an easier manner compared to producing prior art analyte sensors and allows considerably higher tolerances during production.
