1. An implantable bioelectric battery, comprising:

  • an anode electrode;

    a cathode electrode substantially surrounding and separated from said anode electrode;

    a permeable membrane encapsulating said cathode electrode, wherein said permeable membrane is permeable to oxygen and impermeable to body fluid;

    an electrolyte disposed between the cathode electrode and the anode electrode, wherein the electrolyte is less corrosive to the anode than body fluid; and

    a support substrate substantially surrounding the anode electrode, wherein the cathode electrode comprises a wire, and wherein the cathode electrode wire is coiled around the support substrate.
