Academic Degree
Doctor of Engineering
Field of Specialization
electronic materials, organic electronics, sensor technology, electronic device
Outline Activities
Developments of odor and taste sensor have been carried out using functional electronic and organic materials based on nanotechnology and surface science. High sensitive measurement for odor substances or biometrics is the main problem on technical purposes. Qualitative analyses are also important thema of odor and taste sensing. On educational area, functional devices and measurement technology for undergraduate and master course are treated from basic to very advanced matter. Inteligent sensor technology, Inc. USE inc, and IBC inc are co-worker on various sensor system developments. Chemical sensor system society of The institute of electrical engineers of Japan is the main society for investigatiion on sensors.
