It is a versatile, small and sensitive sensor element capable of measuring diversemolecules in the atmosphere and in liquids, including gas molecules and biomolecules. Unlikeconventional nanomechanical sensors, the MSS can achieve high sensitivity with a compact systemthanks to the comprehensive structural optimization with electric read-out based on piezoresistors.Its sensitivity is more than 100 times higher than that of conventional piezoresistivenanomechanical sensors, even surpassing that of optical read-out.The MSS will be utilized for the development of “mobile olfaction” compatible with the emerging“IoT society,” contributing in various fields such as foods, cosmetics, medicine, the environmentand safety, anytime, anywhere and for anybody.To speed up the popularization and practical application of the MSS technology in society, NIMSlaunched an industry-government-academia joint research framework, the MSS Alliance, inhttps://www.nims.go.jp/mana/research/highlights/vol27.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/highlights/vol29.html2022/04/04 10:12 Opening the Way to Mobile Olfaction with Nanomechanical Sensors | MANAhttps://www.nims.go.jp/mana/research/highlights/vol28.html 2/2collaboration with the above-mentioned partners, who possess the key technologies fordevelopment of practical olfaction sensor systems and related services. Through this framework,Dr. Yoshikawa’s research group is working on the challenging tasks of optimizing elementtechnologies and establishing a reliable measurement system toward a de facto standard for anolfaction sensor.Contact informationInternational Center for Materials Nanoarchitectonics(WPI-MANA)National Institute for Materials Science1-1 Namiki, Tsukuba, Ibaraki 305-0044 JapanPhone: +81-29-860-4710E-mail: mana-pr[AT]ml.nims.go.jp
