Abstract

The invention is directed towards an electronic device including at least one electro active polymer element. The at least one electro active polymer element includes an electrode. The at least one electro active polymer element is configured to change volume when a voltage is applied to the electrode, where the change in volume results in a change in a luminous transmittance of the electro active polymer element.
