Field experiments on dielectric elastomer generators integrated on a U-OWC wave energy converter
This paper describes the results of an experimental campaign conducted on a U-Oscillating Water Column (UOWC) wave energy converter equipped with Dielectric Elastomer Generator (DEG) Power Take-Off (PTO) system. The considered PTO technology has the potential for overcoming some of the limitations a...

This paper describes the results of an experimental campaign conducted on a U-Oscillating Water Column (UOWC) wave energy converter equipped with Dielectric Elastomer Generator (DEG) Power Take-Off (PTO) system.
