1. A wireless power charging system, the system comprising:

  • a transmitter configured to transmit power waves into a transmission field of the transmitter; and

    a wearable device, wherein the wearable device comprises;

    one or more antennas configured to transmit data and to receive energy from the power waves in a pocket of energy, wherein the one or more antennas provide the received energy to a receiver for extracting usable power;

    a payload hardware configured to capture one or more measurements in accordance with a payload application of the wearable device, the one or more measurements corresponding to physiologic data of a user of the wearable device;

    a memory configured to;

    store information indicating a maximum power level that the receiver is able to extract from power waves; and

    store the physiologic data; and

    the receiver in electrical communication with the one or more antennas, the receiver comprising a processor configured to;

    measure a power level of the extracted energy;

    determine whether the power level of the extracted energy is less than the maximum power level that the receiver is able to extract; and

    cause the one or more antennas to transmit;

    to the transmitter, data indicating that the receiver requires higher level power waves upon determining that the power level of the extracted energy is less than the maximum power level, andto some electronic device distinct from the transmitter, the physiologic data.
