  Environmental pollution is a recent social problem with offensive odors, and food contamination is also a new social problem. The odor sensing system for detecting and controlling an offensive odor at an early stage is required.
  On using simple monitoring gas sensor in environment measurement, gas detecting tubes and semiconductor gas sensors are widely used in general. The quartz crystal microbalance gas sensor mainly detects gases by an electrode and a thin detection film. Therefore, detection films of the sensor depend on the characteristics of the sensing devices using material and processing technology. In addition, the new analyzers using surface plasmon resonance and millimeter-wave technologies (Terahertz radiation) attract attention.
  The new sensor technologies are expected to detect extremely low concentration from ppm to ppb level with low atmospheric interference.
