1. A system for seismic data acquisition, comprising:

  • a data acquisition unit, comprising;

    a housing, and disposed within the housing;

    circuitry configured to detect and digitize seismic signals; and

    communication circuitry configured to communicate the digitized seismic signals to a data retrieval unit external to the data acquisition unit,the communication circuitry comprising;



    a first transmitter plate; and



    a first driver coupled to the first transmitter plate;

    power receiver circuitry comprising a first coil; and

    the data retrieval unit, comprising;

    a first receiver plate;

    a first receiver coupled to the first receiver plate;

    power transmitter circuitry comprising a second coil, and configured to;

    generate an oscillating magnetic field about the second coil;

    encode in the oscillating magnetic field a location value that uniquely identifies a physical location at which the data acquisition unit is coupled to the data retrieval unit; and

    an alignment structure configured to;

    receive the data acquisition unit; and

    align the first transmitter plate with the first receiver plate to form a capacitor, wherein the housing serves as a dielectric layer between the first transmitter plate and the first receiver plate;

    align the first coil and the second coil;

    wherein the power receiver circuitry is configured to;

    receive, via the first coil, an oscillating current induced in the first coil by the oscillating magnetic field;

    apply the oscillating current to charge an energy storage device that powers the data acquisition unit; and

    extract the location value from the oscillating current;

    wherein the communication circuitry is further configured to append the location value to data acquisition unit identification information to be transmitted to the data retrieval unit via the first transmitter plate.
