Outline of Final Research Achievements

We explored the information processing ability in nano chemical materials. Based on neural network information processing technology, dynamics of response and nonlinearity brought about by the chemical reactions and charge transport in the nanomaterials are expected to be used as a computing resource.
We demonstrated the reservoir computational power in the effects of nonlinear responses and signal dynamics occurring at the interfaces of molecules and carbon nanotube random networks. Furthermore, we found the electrical chemical response in solution is used as the response in reservoir computing. A simple system of nanomaterials and electrochemical reaction in solution was also demonstrated as an AI computing resources.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、安全、安価かつ低消費電力な人工知能デバイスが、我々の最も身近な水とイオンや小さな分子を集合したナノ材料を利用し実現できる可能性が示された。情報量の爆発を抑えつつ快適な未来社会を目指すにはこれまでの半導体素子中心の情報処理方法から脱却した、まったく新しい材料や反応を模索することが求められている。本研究は未来の情報科学技術を切り拓く材料探索の新しい方向性を示した。
