US Patent 7099071 - Carbon Nanotube Actuator
http://www.freepatentsonline.com/7099071.pdf
While issued only last week, this patent from AMBIT Corp. has priority from 1997 and presents a broad claim to electrostatically driven nanotube motion. Companies such as Daiken Chemical of Japan and Nantero of the US are using similar technology to respectively construct nanotweezers and mechanical memory systems. If these technologies take off this patent may become somewhat valuable. Claim 1 reads:
1. A method of moving a carbon nanotube which is attached by one end thereof, to a junction on a substrate, said method comprising: applying a charge to said carbon nanotube; and providing a repelling force to an adjacent structure from said carbon nanotube to which said charge has been applied.
