  • Method of polarizing at least one large area sheet of ferroelectric material
    Patent number: 5700359
    Abstract: A method of polarizing at least one large area sheet of ferroelectric material (1). The method comprises the following successive steps: placing films of ferroelectric material (2, 3) of thickness e.sub.1 against two opposite faces (1a, 1b) of the sheet (1) of thickness e.sub.2, the thickness e.sub.1 being a function of the respective coercive fields of the materials constituting the sheet (1) and the films (2, 3); placing electrodes (4, 5) on either side of and against the films of ferroelectric material (2, 3); compressing the resulting complex; and applying a cyclical voltage between the two electrodes (4, 5).
