Abstract:
1. A coil transducer, comprising: a generally planar electrically insulating substrate comprising opposing upper and lower surfaces, the substrate comprising an electrically insulating, non-metallic, non-semiconductor low dielectric loss material having a dielectric loss tangent at room temperature that is less than or equal to 0.05; a first electrical conductor forming a first coil, the first coil being disposed upon, in or near the upper surface, and a second electrical conductor forming a second coil, the second coil being disposed upon, in or near the lower surface; wherein the first coil is separated from the second coil by at least portions of the substrate, no electrical conductors, vias or terminals are located in portions of the substrate disposed between the first coil and the second coil, the first and second coils are spatially arranged and configured respecting one another such that at least one of power and data signals may be transmitted by the first coil to the second coil across a dielectric barrier comprising the non-semiconductor low dielectric loss material disposed therebetween, the dielectric barrier exceeds about 1 mil in thickness, and a breakdown voltage between the first coil and the second coil exceeds 2,000 volts RMS.
