US Patent 7819005 - Resonant nanotube device

http://www.freepatentsonline.com/7819005.html

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.
