    摘要: The invention relates to a multielement acoustic probe comprising an acoustic support and an electrical circuit with conducting tracks connected to elementary piezoelectric transducers. In addition, the probe comprises a film of composite conducting material placed between the piezoelectric transducers and the conducting tracks. Conventionally, the piezoelectric transducers are subcut in order to obtain elements which are acoustically uncoupled and electrically coupled. The presence of the film of composite conducting material favours the dimensioning of the track with respect to the subelements and constitutes an intermediate element with respect to the differences in thermal expansion between the acoustic support and the piezoelectric transducers. Application: medical and underwater imaging.

    摘要: A unidirectional acoustic probe including a high-performance interconnection network, and a method of manufacturing such a probe. The unidirectional acoustic probe includes linear piezoelectric transducers on the surface of a dielectric film. The dielectric film includes a connection device to electrically connect the piezoelectric transducers to a control device. The connection device includes primary connection pads, facing the piezoelectric transducers, secondary connection pads, offset with respect to the piezoelectric transducers, so that the transducers can be connected to the control device, and conducting tracks connecting the primary connection pads to the secondary connection pads. The conducting tracks are in a direction perpendicular to the direction defined by a major axis of the piezoelectric transducers.
