| titleOfInvention |
Composite ultrasound transducer and fabrication process of a structured component from piezoelectric ceramic |
| abstract |
The composite ultrasound transducer comprises transducer elements (12) which are made of piezoelectric ceramic, radiate essentially in the longitudinal direction and are embedded in a plastic matrix (11). The geometrical structure of the transducer elements (12) and their arrangement with respect to one another is such that any generation of vibration modes perpendicular to the longitudinal direction of the transducer elements (12) in the composite ultrasound transducer is suppressed. The composite ultrasound transducer is produced by a slip casting process using a plastic mould which quantitatively burns without leaving solid residues when the ceramic is fired. In the fabrication process, a plastic mould, in particular, is used which produces any desired structures, in particular hexagonal or irregularly square structures having a trapezoidal cross section parallel to the longitudinal direction, and arrangements of the transducer elements. n<IMAGE> |
