Claim Text:
1. An electrically controllable device comprising: first and second supported electrodes, at least one of which is transparent, which are each formed of a non-conductive substrate coated, on one of its faces, with a conductive coating, the first and second supported electrodes being positioned with respect to one another so that the conductive coatings are facing each other and are in contact with an electrochromic system, the electrochromic system, formed by two electroactive layers, at least one of which is an electrochromic layer, which are separated by a layer of an electrolyte based on an organic polymer, the electrochromic system being sandwiched between the first and second supported electrodes and having an area smaller than that of each of the first and second supported electrodes so as to define a peripheral groove over an entire perimeter of the electrochromic system, a peripheral seal made of an organic polymer that is impermeable to water vapor, said seal filling said peripheral groove over the entire perimeter of the electrochromic system while being entirely in contact both with the first supported electrode and the second supported electrode without being in contact with the electrochromic system, wherein a contact area between the polymer seal and the first supported electrode and a contact area between the polymer seal and the second supported electrode each comprise one or more conductive parts and one or more non-conductive parts, and wherein no conductive part of the contact area between the polymer seal and the first supported electrode is opposite a conductive part of the contact area between the polymer seal and the second supported electrode.
