Rui Yatabe, Atsushi Shunori, Bartosz Wyszynski, Yosuke Hanai, Atsuo Nakao, Masaya Nakatani, Akio Oki, Hiroaki Oka, Takashi Washio, Kiyoshi Toko, Odor Sensor System Using Chemosensitive Resistor Array and Machine Learning, IEEE Sensors Journal, 10.1109/JSEN.2020.3016678, 21, 2, 2077-2083, 2021.01, In this study, we developed an odor sensor system using chemosensitive resistors, which outputted multichannel data. Mixtures of gas chromatography stationary materials (GC materials) and carbon black were used as the chemosensitive resistors. The interaction between the chemosensitive resistors and gas species shifted the electrical resistance of the resistors. Sixteen different chemosensitive resistors were fabricated on an odor sensor chip. In addition, a compact measurement instrument was fabricated. Sixteen channel data were obtained from the measurements of gas species using the instrument. The data were analyzed using machine learning algorithms available on Weka software. As a result, the sensor system successfully identified alcoholic beverages. Finally, we demonstrated the classification of restroom odor in a field test. The classification was successful with an accuracy of 97.9%..
2. Visualization of flavor of sake using taste sensor and gas chromatography-mass spectrometry
© 2020 The Institute of Electrical Engineers of Japan. In the alcoholic beverage industry, expressing "flavor"of sake in an easy-to-understand manner is one of the important issues. So far, we have been conducting equipment analyses using taste sensors and sensory evaluation when people actually drink sake in order to easily understand the "taste"of sake felt by the tongue. By combining them statistically, we have developed the "Sake Flavor Chart". However, the map does not include data on the "scent"of sake. The scent of sake is composed of various ingredients such as banana and apple-like scent called "Ginjo"scent, aged scent, and aldehyde odor, and is a very important factor in expressing the "flavor"of sake. The purpose of this study is to improve the accuracy of the existing sake taste map by comprehensively analyzing the "flavor"of sake using a taste sensor and GC-MS. In this research, "Sake Flavor Chart"becomes a tool that can express not only the "taste"but also the "scent"of sake in an objective and easy-to-understand manner by approaching the flavor of sake from more diverse perspectives than before..

Kiyoshi Toko, Sensors for measuring taste and smell, Brain and Nerve, 69, 5, 557-563, 2017.05, Gustatory and olfactory senses receive chemical substances at the biological membranes of taste and olfactory cells, respectively. The present review article describes electronic tongue (taste sensor) and electronic nose (odor sensor) developed based on biomimetic technology. A taste sensor is now commercially sold and utilized in pharmaceutical and food companies across the world. An electronic nose with high sensitivity was also commercialized in Japan. These sensors provide novel methods for analyzing chemical substances instead of using conventional tools..
