Method and apparatus for providing a disposable power supply source integrated into the housing of the transmitter unit mount that is placed on the skin of the patient, and configured to receive the transmitter unit is disclosed. The transmitter unit mount is configured to be disposable with the analyte sensor so that power supply providing power to the transmitter unit is also replaced. The transmitter unit may include a rechargeable battery that is recharged by the power supply unit of the transmitter unit mount when the transmitter is mounted to the transmitter unit mount. Other energy store configurations including single large capacitor (supercap) or a capacitor and DC/DC converter configurations are disclosed.

What is claimed is: 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. 2. The apparatus of claim 1 wherein the sensor is configured to detect an analyte of the patient. 3. The apparatus of claim 1 wherein the disposable battery includes a silver oxide battery. 4. The apparatus of claim 1 wherein the transmitter unit is configured to transmit one or more signals, where the one or more signals corresponds to a respective one or more signals received from the sensor. 5. The apparatus of claim 4 wherein the transmitter unit is configured to wirelessly transmit the one or more signals. 6. The apparatus of claim 4 wherein the one or more signal received from the sensor correspond to one or more analyte levels of the patient detected by the sensor. 7. The apparatus of claim 6 wherein the one or more analyte levels include glucose levels. 8. The apparatus of claim 1 wherein the electrical contact between the transmitter unit and the sensor is terminated after a predetermined time period when the transmitter unit is decoupled from the transmitter unit mount. 9. An apparatus, comprising: a sensor including an electrical contact portion at a first end and an insertion portion at a second end, the first and second ends of the sensor substantially defining a length of the sensor, the insertion portion of the sensor adapted to be transcutaneously positioned in a patient so as to be in continuous fluid contact with a biological fluid under a skin surface of the patient during a sensing time period, the sensor configured to generate multiple analyte related signals during the sensing time period; a transmitter base including a transmitter base power supply, the transmitter base including a base surface having an adhesive layer, the adhesive layer in contact with the skin surface of the patient when the transmitter base is positioned on the skin surface of the patient, the transmitter base having a housing; and a transmitter unit having a housing which mates with the transmitter base housing, the transmitter unit coupled to the transmitter base power supply of the transmitter base, the transmitter base power supply of the transmitter base configured to provide power to the transmitter unit, the transmitter unit further configured to establish electrical contact with the electrical contact portion of the sensor when mated with the transmitter housing; wherein the adhesive layer retains the transmitter base and the transmitter unit in a substantially fixed position on the skin surface when the transmitter unit housing is mated with the transmitter base. 10. The apparatus of claim 9 wherein the sensor is configured to detect an analyte of the patient. 11. The apparatus of claim 10 wherein the biological fluid includes one of interstitial fluid, lactate or oxygen. 12. The apparatus of claim 9 wherein the transmitter unit is configured to transmit one or more signals, where the one or more signals corresponds to a respective one or more signals received from the sensor. 13. The apparatus of claim 12 further including a receiver unit in signal communication with the transmitter unit. 14. The apparatus of claim 9 wherein the transmitter base power supply includes a disposable battery. 15. The apparatus of claim 14 wherein the disposable battery includes a silver oxide battery. 16. The apparatus of claim 9 wherein the transmitter unit further includes a transmitter unit power supply disposed substantially within the housing of the transmitter unit. 17. The apparatus of claim 16 wherein the transmitter unit power supply includes a rechargeable battery, and further wherein the rechargeable battery is configured to substantially draw power from the transmitter base power supply. 18. The apparatus of claim 9 wherein the electrical contact between the transmitter unit and the sensor is terminated after a predetermined time period when the transmitter unit is decoupled from the transmitter base. 19. An apparatus, comprising: a housing; an analyte sensor coupled to the housing and configured to generate multiple analyte related signals during the sensing time period; a rechargeable battery provided within the housing; a transmitter unit provided within the housing and coupled to the rechargeable battery, the transmitter unit configured to draw power from the rechargeable battery to transmit the multiple analyte related signals to a remote location; and a transmitter unit mount including a disposable battery disposed therein, the transmitter unit mount configured to removably mate with the housing, the transmitter unit mount including an adhesive layer provided on a mount surface for adhering to a skin surface such that the movement of the skin surface does not substantially affect the position of the transmitter unit mount adhered to the skin surface; wherein the rechargeable battery is configured to recharge from the disposable battery disposed in the transmitter unit mount when the housing is mated with the transmitter unit mount.
