1. An apparatus including a data transmission unit, comprising:

  • a sensor including an electrical contact portion and an insertion portion, wherein the insertion portion is adapted for transcutaneous positioning under a skin surface of a patient and for contacting biological fluid under the skin surface, the sensor configured to generate multiple analyte related signals during a sensing time period;

    a transmitter unit mount including a disposable battery and an adhesive layer provided on a mount surface of the transmitter unit mount, the transmitter unit mount configured to be positioned on the skin surface of a patient such that the adhesive layer is in contact with the skin surface and retains the mount surface of the transmitter unit mount in a substantially fixed position on the skin surface, the transmitter unit mount receiving the electrical contact portion of the sensor when the insertion portion of the sensor is positioned under the skin surface and in fluid contact with the analyte; and

    a transmitter unit received by the transmitter unit mount, the transmitter unit including a rechargeable battery, the transmitter unit further configured to establish electrical contact with the electrical contact portion of the sensor, and further, wherein the transmitter unit is configured to draw power from one or more of the disposable battery or the rechargeable battery.
