The Department of Bio-systems Engineering fully uses computers and electronics to clarify and understand the wonderful mechanisms of life systems and also creates artificial systems by applying the superior characteristics. We have conducted a wide variety of studies for our healthy daily lives. We are now working on developing a ubiquitous system that can perform health management "anytime and anywhere."


Designed and prototyped 0.18 μm CMOS LSI chip

"Measuring"

We are developing a system useful for health management that measures fingertip pulse waves and then estimates and calculates the pulse, blood pressure and stress. The natural biological data is measured in ordinary activities such as operating a PC, smartphone, game machine and the like, without the user noticing the measurement, and is analyzed. The system is under development to provide health management with a touch of it and advice as necessary.


"Measuring, processing and transmitting" system

"Processing"

We are designing, prototyping and evaluating the IC chips by ourselves to perform arithmetic processing of measured signals. Our goal is to use a new method called the adiabatic logic circuit technique in order to develop an environmentfriendly ecosystem that is compact and ultra-low power consuming.


Laboratory experiment

"Transmitting"

In the ubiquitous health management system, transmitting data using high-frequency radio communication is indispensable. Thus, we design antennas, signal processing filters, amplifiers and more, implementing them on compact and highly-functional boards.

"Manufacturing"

We are also conducting cooperative research and development with enterprises, and enabling students to create systems useful for society. The students think, design and learn the basics of monozukuri: Japanese manufacturing craftsmanship through constructing and experimenting by themselves.
