Our main aim is to understand highly harmonic and autonomous biological-information systems in order to propose new designing principles for building innovative systems. Biological systems such as human beings can create information necessary to interpret external stimuli and to control actuators in real-time, by appropriately recognizing and judging unpredictable changes in the real-world. To understand how living organisms create information, we study biological mechanisms of object recognition in vision, speaker independent speech recognition, learning and memory in olfaction and voluntary-movement control, with various methods such as psychophysics, neurophysiology, computational simulation, developing robot control system.

1. Mechanisms of learning and memory in olfaction
2. Speaker independent speech recognition by evaluating global spectrum shape
3. Three-dimensional visual recognition by integrating motion vision and form vision
4. Real-time control mechanisms for voluntary movements

For realizing good communication with human body, and for realizing the properties of the human body as a information system, we have to realize the function of the human body as information. We are working on the technology for sensing the information from the human body and for approaching action to the human body. High-frequency carrier-type magnetic field sensor is studied for sensing system for bioinformation. As one of the approaching system for human body, wireless actuators and manipulators are investigated. A part of this technology is applied for a motion system for a capsule endoscope working in the colon tube.

1. Magnetic sensing system
2. Micro magnetic actuators
3. New medical equipments using magnetic

This group is developing high-throughput and sensitive biomedical methods for the analysis of biomolecular interactions and signal transductions by combining semiconductor technology and biotechnology. Attention is mainly focused on development of cell-chips and protein-chips based on semiconductor microfabrication technology. We are also interested in the analysis of biomolecular interactions by using surface infrared spectroscopy and its application to high-throughput drug screening.
