1. A method, comprising:

  • coupling sensor electronics to an inserter and an electrochemical sensor, the sensor electronics operatively coupled to the electrochemical sensor to provide analyte related data to a remote location, the electrochemical sensor configured to generate one or more signals corresponding to monitored analyte levels under a skin surface;

    applying a force on the inserter to insert the inserter and the electrochemical sensor through the skin surface and to position the sensor electronics on the skin surface, the inserter operatively coupled to the electrochemical sensor, the inserter comprising a portion having a sharp structure adapted to support the electrochemical sensor during insertion through the skin surface;

    removing the applied force on the inserter; and

    withdrawing the inserter from under the skin surface while leaving a portion of the electrochemical sensor under the skin surface;

    wherein a portion of the electrochemical sensor inserted through the skin surface protrudes from the sensor electronics positioned on the skin surface; and

    furtherwherein no calibration of the electrochemical sensor is performed after the electrochemical sensor is inserted through the skin surface and during a sensor lifetime including a period of operation of at least one week when the electrochemical sensor is generating signals corresponding to the monitored analyte level under the skin surface.
