Abstract: In order to avoid any risk of detachment where conductors or current paths are provided through the sealing frame (7) which, with the support plates (1,2) defines a chamber (11) enclosed in a seal tight manner at the centre of the cell, the electrodes (3A, 4) situated inside this chamber are connected to respective electrical contacts (6) by means of strips of conductive adhesive (9) extending from the inside to the outside of the chamber. These strips of adhesive may also be used to connect two electrodes to each other.

Abstract: An electric cell comprises first and second parallel flexible substrates, set apart from each other at a determined spacing, carrying electrodes on their opposing faces, the substrates enclosing between them a layer of sensitive material which can change its physical properties, in particular its optical properties, as a result of a voltage applied to the electrodes, or change its electrical properties as a result of stress or radiation passing through one of the substrates, the sensitive material being protected from contact with the atmosphere by a sealing frame which connects, in a sealed manner, peripheral parts of the substrates, said frame having a width parallel to the substrates.
