説明

Recently, environmental pollution is social problem with nano materials and food contamination is a new social problem. On the other hand, the complaint related to the offensive odor in Japan exceeded 20,000 affairs in 1998, and these problems are not solved. The odor sensing system for detecting and control an offensive odor at an early stage is required. The sensing system using the sense of odor known as one of the fifth senses of human is proposed to these demands. Especially as for e-NOSE system, application will be expected from now on in many fields, such as medical diagnosis, health monitoring, environment, food, robot and a car. The sensing technology in which an electrochemical sensor called quartz crystal microbalance (QCM) is mainly used is making detection mechanisms, such as an electrode and a detection thin film on the nano-level. Therefore, detection films of sensor depend on the characteristic of the sensing devices using on material and processing technology. That the new technology sensor is asked can detect extremely low concentration from ppm to ppb level, and it is the sensor with low influence of environment, such as a gas of the outside for detection, temperature and humidity.
