Device, particularly wave power plant for providing electrical energy, has generator unit with electroactive polymer coupled to movable portion of coupling unit and designed to provide electrical energy in response to deformation of polymer

摘要

The device has a coupling unit (104) with a moving portion (122), and an interface for coupling the movable portion of the coupling unit with a section (112) of a chamber (102). The chamber in the operational state is filled with gas in the section and with a liquid in another section (114). A generator unit (106) is provided with an electroactive polymer (134) coupled to the movable portion of the coupling unit and designed to provide electrical energy in response to a mechanical deformation of the polymer caused by the movement of the movable portion of the coupling unit. An independent claim is included for method for providing electrical energy.
