| Outline of Final Research Achievements |
Development of a new rehabilitation technology that substitutes physical functions for patients such as ALS and paralysis with the BMI system is in progress. However, it is considered that there is a limit to the high performance improvement of the intention estimation accuracy in the existing neural activity recording method with only about 100 channels for neurons that have 10 billion in the cerebral cortex. In this research, we develop a multi-channel recording integrated circuit system that achieves both low noise and high integration by combining chopper technology, low crosstalk analog multiplexer technology, and input capacity reduction T type capacity split technology.

| Academic Significance and Societal Importance of the Research Achievements |
従来の神経信号計測ではたかだか100点程度でしかなく、もっと詳細な神経細胞活動を記録したいという要求が本質的にある。本研究はこれにも応じるものであり、将来的には１万、10万チャネルの計測が必要になる可能性もあり、その必要性に迫られるよりも前に、次世代に向けた新しいエネルギーエフィシエントな超多点計測技術の基盤技術を世界に先駆けて開発することに挑戦することで、脳科学における学術的成果に貢献する。
