Patent

CA 2719175

There is provided a transducer array comprising at least one unitary piece of piezoelectric material having first and second opposing surfaces; and a conductive layer on each of said first and second opposing surfaces, wherein at least one of said conductive layers is divided up into a plurality of electrode elements, and wherein said electrode elements, independently, are adapted to receive excitation energy of at least one of a predetermined amplitude and phase.

L'invention concerne une matrice de transducteurs comprenant au moins une pièce unitaire de matériau piézoélectrique comportant une première et une seconde surfaces opposées; et une couche conductrice sur chacune desdites première et seconde surfaces opposées. Au moins une desdites couches conductrices est divisée en une pluralité d'éléments d'électrodes, et lesdits éléments d'électrodes, indépendamment, sont adaptés pour recevoir une énergie d'excitation d'au moins une phase et une amplitude prédéterminées.
