| 摘要 |
The invention relates to a unidirectional acoustic probe comprising a high-performance interconnection network, and a method of manufacturing such a probe. It involves an unidirectional acoustic probe comprising linear piezoelectric transducers (TP1) on the surface of a dielectric film (CIS), said dielectric film comprising means for electrically connecting said piezoelectric transducers to a control device, characterized in that the connection means comprise: primary connection pads, facing the piezoelectric transducers; secondary connection pads, offset with respect to the piezoelectric transducers, so that said transducers can be connected to the control device; conducting tracks connecting the primary connection pads to the secondary connection pads, said conducting tracks being in a direction Dx perpendicular to the direction Dy defined by the major axis of the piezoelectric transducers. The advantage of such a probe resides in the fact that during the shaping step consisting in positioning the probe on a curved support absorbing the acoustic waves, the interconnection network defined is more robust than that according to the prior art.
