A sensor apparatus is disclosed herein. The sensor apparatus includes a flexible carrier that is elongated along a length of the carrier. The sensor apparatus also includes a plurality of analysis zones carried by the carrier. The analysis zones are spaced-apart from one another along the length of the carrier. The sensor apparatus further includes first and second spaced-apart electrodes carried by the flexible carrier. The first and second electrodes have lengths that extend along the length of the carrier. At least one of the first and second electrodes includes analyte sensing chemistry. The first and second electrodes extending across and contact the plurality of analysis zones.
