Odor Sensing

Odor Sensing System

Odor sensing system, called electronic nose or artificial olfaction, uses responses of broadly tuned gas sensors and pattern recognition techniques to distinguish between different odors. Imagine you want to identify wines...

Our odor sensing systems rely mainly on Quartz Crystal Microbalance (QCM) sensors. There are two main research topics involving the QCMs: methods for the QCM sensor fabrication and odor recognition using Short Time Fourier Transform (STFT). QCM technology combined with off-the-shelf odor sensors is used in our research on halitosis. Recently we have engaged in research on spherical Surface Acoustic Wave devices, so called Ball-SAWs. We have also been working on odor sensing systems employing gas detector tubes and LEDs.
