| Outline of Final Research Achievements |
Information about the depth as well as the voltage of the biosignal source can be retrieved by switching the voltage dividing resistance placed between signal electrode and ground electrode. This study consists of 6 research subthemes; 1) theoretical study of this high-speed voltage divider switching electrode and development of a measurement system with one electrode, 2) development of multi-channel voltage divider switching electrode system, 3) development of 3-dimensional biosignal distribution estimation method, 4) improvement of measurement accuracy by switching of ground position, 5) application for the separation of inner muscle EMG, 6) application for the measurement accuracy improvement of event-related potential. We have succeeded to obtain fruitful outcomes in each subthemes.
