Abstract: An electrically controllable device includes two supported electrodes, each coated with a conductive coating, the two electrodes positioned with respect to one another so that the conductive coatings are facing each other. An electroactive system, sandwiched between, and in contact with, the two electrodes, has an area smaller than that of each of the electrodes to define a peripheral groove over the entire perimeter of the electroactive system. A peripheral seal fills the groove over the entire perimeter of the electroactive system and is entirely in contact with the two electrodes. The contact area between the seal and the first electrode and the contact area between the seal and the second electrode each include a conductive part and a non-conductive part. No conductive part of the contact area between the seal and the first electrode is opposite a conductive part of the contact area between the seal and the second electrode.
