Patent

CA 2154666

A method for producing a piezoelectric component, and the resulting component, are disclosed. The production method includes stacking at least one piezoelectric element (1) and two or more metal electrodes (2), each piezoelectric element (1) being inserted between two metal electrodes (2). Each piezoelectric element and each metal electrode are produced by winding a piezoelectric film and a metallised film, respectively.

L'invention concerne un procédé de fabrication de composant piézoélectrique ainsi que le composant issu d'un tel procédé. Selon l'invention, le procédé de fabrication comprend l'empilement d'au moins un élément piézoélectrique (1) et d'au moins deux electrodes métalliques (2), chaque élément piézoélectrique (1) se trouvant inséré entre deux électrodes métalliques (2), caractérisé en ce que chaque élément piézoélectrique et chaque électrode métalique sont réalisés, respectivement, par le bobinage d'un film piézoélectriqe et par le bobinage d'un film métallisé.
