全貼付型触覚デバイスの創製を可能にする超薄型PVCゲルアクチュエータの開発

R6年度は、可塑剤（アジピン酸ジブチル（DBA），アジピン酸ジオクチル（DOA））を含有したポリ塩化ビニル（PVC）ゲル超薄膜（ナノシート）の作製と単層カーボンナノチューブ（SWCNT）をPVCゲルナノシートの片面に塗布したSWCNT-PVCゲルナノシートの作製を検討した。具体的には、グラビアコート法を用いてPVCゲル（PVC:DOA: =1:6）ナノシート（VCDOA14G）を得た。また、バーコート法を用いて20 μm程度の膜厚を有するPVCゲル（PVC:DBA =1:4）シート（VCDBA14B）を作製した。さらに、SWCNTインクをPVCゲル（PVC:DBA =1:6，PVC:DOA =1:6）ナノシート上に塗布し、乾燥させることで導電性ナノシート（SWCNT-VCDBA16G，SWCNT-VCDOA16G）を作製した。得られた、VCDOA14G、VCDBA14B、SWCNT-VCDBA16G，SWCNT-VCDOA16Gを用いて2種類のPVCゲルアクチュエータを作製した。一つは、一枚のVCDOA14Gを二枚のSWCNT-VCDOA16Gで挟んだ単層アクチュエータを作製した。このアクチュエータを直流安定化電源に接続し、30.7 Vの電圧を印加したところ拡張・収縮挙動を確認した。もう一つは、三枚のVCDBA14B、四枚のSWCNT-VCDBA16Gを一枚ずつ交互に積層したアクチュエータを作製した。このアクチュエータをマルチファンクションジェネレータと高電圧アンプ，Arduino UNO R3を含む充電電流、電圧計測用回路に接続し電圧印加試験中の電流値、印加電圧を記録し、ビデオカメラでアクチュエータの変形挙動を観察した。印加電圧130 Vで面内方向に60 μm程度の変位量を示した。この値は、皮膚の伸展を感受するルフィニ小体の知覚閾変位量（40 μm）よりも大きかった。

Development of a weaving machine that enables semi-automatic fabrication of textile structural actuators

In recent years, numerous studies have been reported on the development of low-voltage drive and efficient manufacturing methods for soft actuators using dielectric gels and dielectric elastomers such as PVC gel, which are expected to be applied to artificial muscles and tactile sensation presentation devices. In this study, we designed a weaving machine that enables semi-automatic production of woven PVC gel actuators.
Subsequently, we evaluated the fabrication of a laminated dielectric elastomer actuator (DEA) that can be applied to tactile presentation devices and can be applied to the skin, and developed a capacitive thin-film strain sensor that can be applied to the skin. By combining the sensor with a wireless unit, it became possible to measure body movements (finger flexion and extension, swallowing) in real-time.
