US Patent 7982570 - CNT-enhanced inductor

This patent from General Electric teaches how carbon nanotubes can be used to enhance the Q-factor (a measure of energy storage versus energy dissipation) of inductors used in magnetic resonance imaging. Claim 1 reads:

1. An inductor comprising an electrical conductor wound in a magnetic flux concentrating pattern, the electrical conductor comprising:

a substrate formed into a shape of the inductor; and

a plurality of carbon nanotubes substantially aligned with an axis along a center of the electrical conductor, wherein the plurality of carbon nanotubes are grown on the substrate.
