Leader: Prof. Yayoi Satsumoto

The task of this division is to establish social infrastructure for the future safe and reliable community using advanced technologies based on information communications technology, biology and medical engineering. This division is composed of four research fields, that is, gMedical Information and Communication Engineeringh, gBio-Medical Scienceh, gBody Information Engineeringh and gPromotion for Medical Collaborationh. Every staffs of these divisions are cooperating and collaborating with each other to achieve the above aim.

(1) Field of Medical Information and Communication Engineering

We try to explore new interdisciplinary research fields of medical engineering by studying advanced information and communication technologies. Our research themes cover the wide research fields from physical layer to upper layer, inside and outside of the biological body. Especially, UWB (Ultra Wide Band) based sensor network technology will be able to become an international standard of BAN (Body Area Network). We are also researching on radio propagation measurement between implanted modules, UWB ubiquitous medical care system, hyperthermia using micro coils and MRI, creation of gSocio-technical environmenth with distributed intelligent system, 24-hours health care system, medical data mining, medical image processing and so on.

(2) Field of Bio-Medical Science

The activity of the field is supported by the staffs who have a close relationship to biology rather than communication and information technologies. In order to develop a medical system, a hierarchical research program is performed from novel nanoparticles and its derivatives effect on cell differentiation, new methodology on biomarkers detection, to novel system synthesizing biomarkers for stress as well as non-invasive assessment from human body.

(3) Field of Promotion for Medical Collaboration

This field consists of several experts of Social Sciences, Economics, Education, Health Services and ICT.  A lot of social, legal and commercial themes concerned with medical ICT, such as medical malpractices, ethics, laws, hospital management and business models have been discussed repeatedly in this field.

Division of Communication Network Systems
 
 @@@@@@@@@@@@@  Leader: Prof. Hideki Ochiai

There are three fields of research area in the division of communication network system. The first one is information communication system design, the second one is information communication network design, and the last one is the frontier of communication system. Ultimate research goal of the division is to establish a basis of optical and electro-magnetic information communication network, and to propose a new application of communication technology based on a fusion of hardware and software of the communication system

(1) Field of information and communication system design

Our research field is not only in the evolution of core technology on the physical layer such as UWB, SDR, MIMO, array processing, and OFDM, but also in the hardware implementation of UWB communication unit for development of Body Area Network (BAN) inside and outside the biological body.  We will develop physical and media access control layers for BAN. We will also evaluate the effect of BAN on the human body as well as the communication performance such as the bit error rate and throughput since its application is a medical instruments. We will also develop a wireless system at low cost for short range communication around the human body.

(2) Field of information and communication network design

We are researching on network and link technologies in the medical field. The network and link technologies can be applied to various fields. Our main focus is on sensor link technology which is suitable for the size of body, and sensor localization technology in the biological body with high electro-magnetic attenuation. In the field of local government, we will design the ubiquitous medical information network by employing GPS for real time field analysis of infectious disease. We will develop a core network system that is able to treat an event immediately at the beginning and expansion process of new infections disease. The core network can be deployed at any kind of field adaptively.  The system will be developed as open source for collaborative development.

(3) Field of Information and Communication Frontiers

Based on our scholarly attainment in software engineering, data mining, mobile agents, biometric authentication, and cryptographic technologies, we study Software and Security Engineering issues in realizing the following medical care related systems and services with strong societal demand; (1) Lifelong healthcare management systems with emphasis on security and privacy, (2) Privacy-enhanced medical information and consulting services, (3) Database systems to support both patients and medical staffs, and (4) Information systems to eliminate error and enhance safety in medical treatment.

In order to process a large amount of information explosively increasing recently, further progress in electronic and optoelectronic device technologies and their system integration are absolutely needed. In our studies, we focus on the following topics. Single-flux-quantum integrated circuits, low-temperature semiconductor integrated circuits, and integrated circuits based on quantum computation devices are expected to be core technologies for next-generation ultrahigh-speed information processing. Transistors and non-volatile memories based on ferroelectric materials, and new-functional integrated systems are attractive to realize highly developed integrated circuits. Fabrication and characterization of compound semiconductor quantum dots pioneer emerging quantum devices based on new physical mechanism. Semiconductor high-speed devices for all-optical signal processing will be a key technology for future high-speed signal processing. The aim of these studies is to develop next-generation high-performance integrated systems, and they will contribute to high-quality medical information communication.

(3) Nano-devices and nano-sensors

We aim to develop electron devices and bio-sensors which are the base of the medical information communication. In particular, we focus on the following subjects for realizing bio-nano technology-based devices and sensors which are useful in the practice of medicine; carbon nanotube networks for biosensors, micro-actuators and micro-sensors fabricated with 3D micro-nano formation technology for medical diagnoses and treatment, nano-fiber measurements without diffraction limit and femto-second laser spectroscopy, magneto-optical functional devices using optically induced phenomena for new application to medical and biological fields.
