Title: ENERGETIC PULSE CLEARING OF ENVIRONMENTALLY SENSITIVE THIN-FILM DEVICES
Abstract:
A process and electronic hardware and software system for rapidly heating and cooling an active sensing layer of a gas sensor is provided. A series of high-energy pulses is run through a CNT electrically-active layer, heating the layer to varying temperatures. The influence by various gases on the electrical conductivity of the layer can be used to identify gases (e.g., water vapor, alcohol, methane, O2, CO2, and CO). Advantageously, the same structure can also be used as a nanoheater, either within or outside the context of the gas sensor. The device can acquire a unique gas spectra in seconds, and thus accurately determine gas type and mixtures of gases based on a library of known spectra.
