Abstract

Se provee un transductor acústico de barra curva capaz de excitar al menos tres modos de resonancia. El transductor acústico de barra curva puede ser capaz de excitar un segundo modo de resonancia al configurar una primera parte de un elemento piezoeléctrico para que se contraiga, mientras que una segunda parte del elemento piezoeléctrico se expande cuando se aplica voltaje a los electrodos acoplados al elemento piezoeléctrico. Es posible configurar adicionalmente el transductor acústico de barra curva de manera que la primera parte y la segunda parte del elemento piezoeléctrico se contraigan y/o se expandan para excitar un primer modo de resonancia. Se puede utilizar el transductor acústico de barra curva en aplicaciones de adquisición de registros y en el fondo de pozo.
