Hitoshi Tabata



Challenging Medical Engineering with Quantum and Nanoelectronics



Purpose of Research

We are researching electronics that learn" from bio-system and learn "about" bio-system. In the former theme, we focus on the fact that the physical description of neuron signal processing can be described by a Hamiltonian, the same as the spin glass, a spin fluctuation physical property, and we are developing and studying brain-like devices utilizing spin fluctuation. In the latter theme, we have created an ultra-sensitive skin gas sensor using semiconducting nanotechnology and are developing a wearable healthcare sensor (sniffing device) for smartwatches to realize an undiseased and ultra-early diagnosis. In addition, we are developing non-fluorescent labeling, non-invasive inspection, and diagnostic technologies for selective coherent excitation, hydration state by plasmon, and intermolecular bonding using infrared region light represented by THz waves based on Dirac electron system.

Subjects of Reseach
