    摘要: A portable sensor device incorporates a low-power, nanostructure sensor coupled to a wireless transmitter. The sensor uses a nanostructure conducting channel, such as a nanotube network, that is functionalized to respond to a selected analyte. A measurement circuit connected to the sensor determines a change in the electrical characteristic of the sensor, from which information concerning the present or absence of the analyte may be determined. The portable sensor device may include a portable power source, such as a battery. It may further include a transmitter for wirelessly transmitting data to a base station.

    摘要: A nanoelectronic sensing device includes a substrate, a nanostructure element disposed adjacent the substrate, and at least a conductive element electrically connected to the nanostructure element. The device is configured to heat at least a portion of the sensor structure including the nanostructure element. In certain embodiments, the nanostructure element comprises at least one nanotube, the nanotube being electrically connected to at least two conductors so as to permit an electric current on the order of 10 microAmps or greater to be passed through the nanotube, causing the nanotube to heat up relative to the substrate. In alternative embodiments, the sensing device includes a platform or membrane which is at least partially thermally isolated by one or more cavities, the platform supporting at least the nanostructure element adjacent to a microheater element. The heating of the sensor structure may be employed, for example, for thermoregulation, to accelerate and/or increase sensor response, and to improve other sensor characteristics.
