Procédé pour polariser au moins une zone d'une feuille de matériau ferroélectrique et application du procédé pour réaliser un élément polarisé pour capteur piézoélectrique ou pyroélectrique.

摘要

A method of polarizing selected areas of a foil of ferroelectric material, wherein electrodes are deposited in such a way on the opposite surfaces of the foil that the zone to be polarized extends between these two electrodes. The zone to be polarized is compressed and a variable voltage is applied across the electrodes. Each electrode is connected to an insulating support whose surface exceeds that of the zone to be polarized on the foil of ferroelectric material. Besides the electrode, the insulating support has a layer of dielectric material whose external surface is level with the external surface of the electrode.
