Outline of Research at the Start

ソフトアクチュエータである誘電エラストマーアクチュエータの実用化を阻む本質的問題点は低発生力にあり,この問題を解決するために、「高剛性化」に加え,「低起動電界化」,「高絶縁耐力化」に基づく入力電界範囲拡張により大発生力を実現する.下記3テーマを軸とする.
【テーマ1】高誘電粉体のマイクロコンポジットによる高剛性化・低起動電界化
【テーマ2】ナノクレイのナノコンポジットによる変形層の高絶縁耐力化
【テーマ3】電極層のスーパーキャパシタ化による低起動電界化(先行研究成果の発展)

Outline of Final Research Achievements

In a dielectric elastomer (polyurethane: PU) filled with barium titanate (BaTiO3) and added with nanoclay (NC), the effect of the addition of a surfactant on the dispersibility, dielectric constant, insulation breakdown electric field, and DEA performance of BaTiO3 and NC. Was investigated. It was found that the strain of barium titanate-filled polyurethane (BaTiO3 / PU) at 8 V / μm was larger than that of unfilled PU due to the composite of BaTiO3 in the surfactant-added system. It was also found that the insulation breakdown electric field of barium titanate-filled polyurethane (BaTiO3 / NC / PU) with NC added was higher than that of BaTiO3 / PU with the addition of NC in the system without surfactant.

Academic Significance and Societal Importance of the Research Achievements

本研究は,ソフトアクチュエータの一種である誘電エラストマーアクチュエータ(DEA)の実用化を阻む本質的問題点(低発生力)を解決することを目的に,「高剛性化」,「低起動電界化」,「高絶縁耐力化」に基づく入力電界範囲拡張を目指すものである.また、同時に機械的動特性と電気的特性も明らかにし、セルセンシング・アクチュエーションの可能性も明らかにした。これらの得られた知見は複合系DEA の現象理解を促進しうるものであり、センサーとアクチュエータ両方の機能をもった革新的なソフトアクチュエータとしての可能性を示した。
