Patent ID: 8822843

Claim:
A printed wiring board, comprising: a conductive layer, the conductive layer comprising a network of multi-walled carbon nanotubes with respective longitudinal axes, the nanotubes arranged such that their longitudinal axes are aligned substantially parallel to one another in a configuration such that electrical current passing through the conductive layer along a first axis substantially parallel to the longitudinal axes of the nanotubes experiences one degree of dissipation, and electrical current passing through the conductive layer along a second axis substantially perpendicular to the longitudinal axes of the nanotubes experiences a higher degree of dissipation; and a signal strip arranged with the conductive layer; wherein the substantially perpendicular alignment of the second axis to the longitudinal axes of the nanotubes is configured to conduct current away from the signal strip; wherein the conductive layer is configured to have an anisotropic electrical conductivity with a ratio of up to 10:1 along the first and second axes, respectively.
