ABSTRACT:
Devices usable as sensors, as transducers, or as both sensors and transducers include one or more nanotubes or nanowires. In some embodiments, the devices may each include a plurality of sensor/transducer devices carried by a common substrate. The sensor/transducer devices may be individually operable, and may exhibit a plurality of resonant frequencies to enhance the operable frequency bandwidth of the devices. Sensor/transducer devices include one or more elements configured to alter a resonant frequency of a nanotube. Such elements may be selectively and individually actuable. Methods for sensing mechanical displacements and vibrations include monitoring an electrical characteristic of a nanotube. Methods for generating mechanical displacements and vibrations include using an electrical signal to induce mechanical displacements or vibrations in one or more nanotubes. Methods for adjusting an electrical signal include passing an electrical signal through a nanotube and changing a resonant frequency of the nanotube.
