Abstract: This paper introduces a theoretical and experimental study of a wave energy converter (WEC) that combines the two innovative concepts of U-oscillating water column (U-OWC) and dielectric elastomer generator (DEG) power take-off (PTO). The U-OWC is a type of oscillating water column that features a U-shaped duct that is introduced to tune its dynamics to a certain wave period without active means of phase-control. The DEG is a compliant polymeric generator that makes it possible to convert mechanical energy into electrical energy by exploiting the large deformations of elastomeric membranes.
