Electronic Engineering

About Electronic Engineering

Electronic engineering is widely used in modern society’s infrastructure. Department of Electronic Engineering studies involve two specialized fields -materials and devices and intelligent information processing circuits- in conformance with Japan Accreditation Board for Engineering Education (JABEE) training programs to develop the ability to respond to continuing advances in electronics as industry and society change.

Research

In this laboratory, we focus on the functional measurement of brain activities and its application to the daily life. The brain activities measured by EEG (electroencephalogram), functional NIRS (near-infrared spectroscopy) or fMRI (functional magnetic resonance imaging) are analyzed to uncover higher-order brain functions. As an application of the biosignal measurement, we are studying on the brain-computer interface (BCI), on which the intentions or “thoughts” of human are extracted from brain activities and the measured signals are used to modulate brain activities via neuro-feedback technology. The BCI will enable us to communicate between brain and external world bi-directionally. Moreover, we are also developing the eyewear “JINS MEME” with an eyewear company, to enable precise detection of mental and physical states of users in a daily life. The mental (drowsiness, sleepiness, fatigue, interest) and physical states can be identified from the EOG (electrooculogram) signal and the body motion measured by this eyewear. This device can enable you to look into “yourself”, as well as outer scenes.

Our laboratory researches applications of ultrasonic wave and a sensor, Global Navigation Satellite Systems (GNSS).One of our research is the development of unmanned underwater explorer system. At present, we developed free fall type underwater observatory system named ‘Gyogyotto camera’, which enables us to observe the sea bottom through long distance with Wi- Fi and LAN. The system also can capture all around video. In order to apply the system to exploring resources in the sea bottom or to protecting marine resources, the underwater positioning is required. In general, high-performance inertial sensor is necessary for positioning in the sea due to unavailability of GNSS. However, precision of inertial sensor depends on dimensions and cost. We try to improve the precision of the underwater positioning system using low cost and compact inertial system with the aid of video analysis and ultrasonic wave. We expect more various users take part in the marine engineering field due to the realization of the developed systems.

Objectives in Education and Research

The vision of the Department of Electronics Engineering is to cultivate individuals with the following skills:

  1. Fundamental knowledge/applied skills: Acquire fundamental knowledge in electronics engineering expertise (Materials and devices/logic circuits) and apply expert knowledge.
  2. Self-expression/conversation skills: Presentation skills and communication abilities necessary to theoretically express ones own views.
  3. Behavior, intentions, cooperativeness, sense of ethics and responsibility.

Career

Electronic Engineering is fundamental in supporting our present society and vital for technology. The graduates are therefore proactively employed not only in manufacturing industries such as electric and electronic, automobile, chemistry, and machinery, but are also employed in the social infrastructure industries including railway, information communications, media, energy, and construction as well as foods/agriculture-related fields.
