1. A method, comprising:
- generating a magnetic field at a receiver unit during a time period associated with data communication between sensor electronics and the receiver unit, wherein generating the magnetic field is programmed to turn on or turn off only during the time period, and wherein the sensor electronics is operatively coupled to an analyte sensor in fluid contact with interstitial fluid, wherein one or more signals are generated by the analyte sensor and associated with a monitored analyte level;
inductively coupling a rechargeable power source of the sensor electronics when the sensor electronics is placed within a predetermined distance from the generated magnetic field during the time period associated with the data communication; and
communicating data associated with the monitored analyte level from the sensor electronics to the receiver unit during the time period.
