1. A bio-medical unit for implanting into a body, the bio-medical unit comprises:

  • a power harvesting module operable to generate a power supply voltage from a modulated magnetic resonance imaging signal;

    an electromagnetic communication module powered by the power supply voltage and operable to;

    receive the modulated magnetic resonance imaging signal;

    recover a downstream electromagnetic communication signal from the modulated magnetic resonance imaging signal, wherein the downstream electromagnetic communication signal is modulated on a magnetic resonance imaging signal generated by a magnetic resonance imaging device for imaging to produce the modulated magnetic resonance imaging signal;

    convert the downstream electromagnetic communication signal into downstream information;

    convert upstream information into an upstream electromagnetic communication signal; and

    transmit the upstream electromagnetic communication signal;

    a processing module operable to;

    convert the downstream information into at least one of downstream data and a downstream instruction; and

    convert at least one of an upstream instruction and upstream data into the upstream information; and

    a function module operable to;

    generate the at least one of an upstream instruction and the upstream data; and

    perform a bio-medical function based on the at least one of downstream data and the downstream instruction.
