Patent ID: 8112157

Claim:
A device comprising the following components: a) a conductive material configured to produce an electromotive force in the presence of a predetermined magnetic field density, wherein the predetermined magnetic field density is a modulated magnetic field specific to data transmission; b) a magnetic material comprising a metal alloy selected from the group consisting of Perm-magnetic material, Fe—Ni magnetic material, Mo-perm-magnetic material, Mu-metal, M-1040, supermagnetic material and ultraperm configured to, in the presence of the predetermined magnetic field density, increase magnetic field density in proximity to the conductive material and induce an electromotive force in the conductive material that is higher with the magnetic material than without the magnetic material; c) a polymeric material configured to provide chemical resistance and a barrier to moisture and oxygen, wherein the magnetic material and the conductive material are encapsulated in the polymeric material, wherein the conductive material is surrounded by the magnetic material, wherein the conductive material and magnetic material are separated from one another by polymeric material such that the magnetic material increases the magnetic field density in proximity to the conductive material and wherein the components are assembled to provide a coil device comprising at least one structure that functions as a radio-frequency coil.
