Outline of Research at the Start

動物やヒトが外界を感知するための五感は、感覚機能として生活に欠かせない。生体系の触力覚では、ソフトマターの協同性により、機械的刺激を受けたタンパク質等の高次階層構造が変化することで、イオンチャネルが見事に制御されている。これに対して、人工的な触力覚センシングは、電子輸送に基づいたものが多く、イオン伝導性を用いた階層的構造の設計指針が確立していない。
本研究では、2名の研究分担者とともに、階層的構造を有するスルホン化ポリイミドにおけるイオン輸送の研究実績を活かして(Sci. Tech. Adv. Mater., 21, 79 (2020))、イオン伝導性が機械的負荷に応答した起源を解明する。

Outline of Final Research Achievements

In this study, we examined the responsiveness of ion conductivity to mechanical loads applied perpendicular to the surface of sulfonated polyimide membranes organized by lyotropic liquid crystallinity. Using a developed measurement apparatus, we confirmed that the resistance of proton conductivity increased linearly with pressure, particularly identifying membranes that exhibited a sensitivity of 24 MPa^-1, an order of magnitude higher than conventional materials. We found that the response varied depending on the structure of sulfonated polyimide and the ion species in the side chains. The enhancement of structural periodicity and reparability of organization under hydration increased the sensitivity and responsiveness of ion conductivity. This outcome enabled the development of novel sensor materials utilizing lyotropic liquid crystallinity.

Academic Significance and Societal Importance of the Research Achievements

本研究は、スルホン化ポリイミド膜のイオン伝導性が機械的負荷に応答することについて、リオトロピック液晶性を用いた分子組織化を用いた、生体に近い触力覚センシング技術を切り開いた点で学術的意義を持つ。特に、高次構造の周期性がイオン伝導性の抵抗変化や感度に影響を与えることを見出した知見はインパクトがある。社会的には、この知見はより生体に近いメカニズムを有する触力覚センサなどのウェアラブルデバイスやヘルスケアアプリケーション、人間の皮膚のような高感度かつ自己修復可能なセンシング材料の実現が期待され、未来のロボティクスや医療技術に革新をもたらすことが期待される。
