Title (EN) PIEZOELECTRIC TRANSDUCERS
(FR) TRANSDUCTEURS PIEZOELECTRIQUES
Abstract: front page image
(EN)Piezoelectric transducers for high power applications are detailed that comprise a plurality of piezoelectric layers (18, 20) and a plurality of shims (30, 32) that are in a sandwich structure, and in which the shims (30, 32) extend substantially beyond the piezoelectric layers. The shims may also function as electrodes and they provide the cooling means for the transducers.
(FR)L'invention concerne des transducteurs piézoélectriques destinés à des applications de puissance élevée, comportant une pluralité de couches piézoélectriques (18, 20) et une pluralité de cales (30, 32) en structure sandwich, lesdites cales (30, 32) s'étendant essentiellement au-delà des couches piézoélectriques. Lesdites cales peuvent également fonctionner en tant qu'électrodes et servent d'éléments de refroidissement pour les transducteurs.
