1. A miniaturized in-body electronic device comprising:

  • at least one antenna galvanically coupled to receive an AC signal through the body of a subject where the in-body electronic device is located;

    power extraction circuitry configured to extract electrical power at least from the AC signal received by the antenna, the extracted electrical power being accumulated over a charging cycle;

    a transmitter coupled to receive power from the power extraction circuitry; and

    a controller coupled to the transmitter, wherein the controller is configured to activate the transmitter to generate a sequence of intermittent transmission bursts for transmitting an uplink signal, wherein a transmission burst comprises a power level consistent with the amount of electrical power being accumulated over the charging cycle.
