US Patent 7354877 - Superconducting CNT Faraday Cage

A Faraday cage is a conductive enclosure which protects electronics from external electromagnetic interference. This patent from Lockheed Martin teaches a Faraday Cage garment formed of superconducting carbon nanotubes. Claim 1 reads:

1. A garment made of fabric, wherein said fabric comprises: a first layer of yarns woven to form the fabric wherein said yarns comprise at least one carbon nanotube fiber and wherein said carbon nanotube fiber comprise single-walled carbon nanotubes and/or multi-walled carbon nanotubes; and at least one additional layer of yarns woven together, wherein said first layer comprises yarns of superconductive carbon nanotube fibers that form a Faraday cage and wherein said at least one additional layer of yarns woven together comprise insulating carbon nanotube fibers.
