透明ソフトアクチュエータの三次元造形に向けた検討

抄録

Dielectric elastomer actuators (DEAs) are intensively researched because of their fast response, large deformation, and good control characteristics. However, these actuators are conventionally fabricated in non-transparent body and two-dimensional structure. In this study, we perform basic evaluation of transparent DEA toward three-dimensional fabrication and actuation. The actuators are made of silicone elastomers that are transparent and have high mold transfer characteristics. For the basic evaluation, the driving characteristics of the membrane samples under pre-stretch were evaluated. Furthermore, we constructed driving system of the actuator for three-dimensional motion by using water pressure. We evaluated displacement ratio and frequency response of both actuators.
