1. An article configured to be worn on shoulders and an upper portion of a user'"'"'s torso, comprising:

  • at least one piece of material configured to conform to the shoulders and the upper portion of the user'"'"'s torso;

    a first resonator attached to the at least one piece of material and comprising a conductive coil formed by a plurality of planar loops each positioned in a first plane to define a dipole moment for the first resonator that is aligned orthogonal to the first plane, wherein the first resonator is configured to wirelessly receive electrical power from an oscillating magnetic field;

    a battery attached to the at least one piece of material;

    an electrical apparatus attached to the at least one piece of material and coupled to the first resonator and the battery, and configured to store energy in the battery in response to the electrical power wirelessly received by the first resonator; and

    a second resonator coupled to the battery and configured to transmit electrical power by generating an oscillating magnetic field using power from the battery,wherein the second resonator is attached to the at least one piece of material at a location proximal to an opening in the at least one piece of material configured to at least partially surround a neck of the user; and

    wherein the second resonator comprises a helical coil comprising a plurality of loops of conductive material that extend along an arc-shaped helical axis.
