ABSTRACT:
The structure comprises an electrically and thermally insulating polyimide layer, infrared sensors which are insulated from one another and have a polyvinyl pyroelectric film, whose face in contact with the polyimide is equipped with two comb-shaped electrodes, whose teeth are imbricated, the pyroelectric film being polarized in a plane parallel to the film and in directions parallel and perpendicular to the comb teeth, an integrated circuit having a face in contact with the polyimide layer, equipped with the reading circuit, and electric contact zones completely traverse the polyimide layer and connect the electrodes of each sensor to a reading circuit.
