1. An analyte monitoring system, comprising:

  • an analyte sensor comprising a substrate, at least one electrode disposed on a first side of the substrate and at least one electrode disposed on a second side of the substrate opposite the first side, wherein the electrodes are in fluid contact with an interstitial fluid of a user when at least a portion of the substrate is transcutaneously positioned within the user; and

    an on body unit operatively coupled to the analyte sensor and configured to receive one or more signals from the sensor corresponding to an analyte level of the user, wherein the on body unit is electrically connectable to the first side of the substrate by a first electrical connection and is electrically connectable to the second side of the substrate by a second electrical connection;

    wherein an external surface of the on body unit comprises at least one conductive point in electrical contact with an external electrode, wherein the at least one conductive point physically contacts the user'"'"'s skin when the on body unit is operatively coupled to the transcutaneously positioned sensor.
