| Outline of Final Research Achievements |
An opto-electric brain machine interface based on the planned concept was successfully developed. The device has following features:
1, The device has a structure consisgting of multiple unit devices connected with flexible bridge structure. The strcuture can be bent two-dimensionally. 2. Each unit device is equipped with dedicated CMOS control chip. The chip can be used as a selector for multiple LED or neural electrodes on each unit device. 3. Each CMOS chip on the unit device has its unique ID and identification sequence. So multiple CMOS chip connnected on shared bus wirings (5-6 wires) can be consistently operated.

本研究により、CMOS集積回路の高機能性・多チャンネルスイッチング性を利用しながら、広い範囲で、かつ2次元屈曲可能なブレイン・マシン・インターフェース(BMI)の有効な形態を提示することができた。今後、本研究で開発した技術を新たなデバイス開発に有効利用することができる。特に光と電気を両方用いるというコンセプトは、今世紀に入って大きく発展した光遺伝学(オプトジェネティクス)を取り込んだBMI技術のニーズにこたえることができると期待する。
