US Patent Issued to Nantero on June 21 for "Carbon Nanotube Resonators Comprising a Non-Woven Fabric of Unaligned Nanotubes" (Virginia, Massachusetts Inventors)

ALEXANDRIA, Va., June 27 -- United States Patent no. 7,965,156, issued on June 21, was assigned to Nantero Inc. (Woburn, Mass.).
 
"Carbon Nanotube Resonators Comprising a Non-Woven Fabric of Unaligned Nanotubes" was invented by Jonathan W. Ward (Fairfax, Va.) and Brent M. Segal (Woburn, Mass.).

According to the abstract released by the U.S. Patent & Trademark Office: "Under one aspect, a resonator 400 includes a nanotube element 410 including a non-woven fabric of unaligned nanotubes and having a thickness, and a support structure 404 defining a gap 406 over which the nanotube element 410 is suspended, the thickness of the nanotube element 410 and the length of the gap 406 being selected to provide a pre-specified resonance frequency for the resonator 400 The resonator 400 also includes a conductive element 412 in electrical contact with the nanotube element 410, a drive electrode 408 in spaced relation to the nanotube element 410, and power logic in electrical contact with die at least one drive electrode 408 The power logic provides a series of electrical pulses at a frequency selected to be about the same as the pre-specified resonance frequency of the resonator 400 to the drive electrode 408 during operation of the resonator 400, such that the nanotube element 410 responds to the series of electrical pulses applied to the drive electrode 408 by making a series of mechanical motions at the resonance frequency of the resonator 400."
 
The patent was filed on Sept. 5, 2006, under Application No. 12/065,854.
