US Patent 7819005 - Resonant nanotube device


This patent from Micron Technology exploits the property of carbon nanotubes that mechanical deformation alters resistivity thus allowing for the creation of new nanotube sensors and transducers. Claim 1 reads: 

1. A sensor/transducer device, comprising:

at least one nanotube having a first end structurally and electrically coupled to a first electrode and a second end structurally and electrically coupled to a second electrode; and

at least one element configured to selectively adjust a resonant frequency of the at least one nanotube;

wherein the at least one element comprises at least one piezoelectric element.
