Morgan Technical Ceramics offers a range of piezoceramic composite materials to improve the performance of ultrasound and sonar transducers in medical, biometric, military and industrial applications.

As a result of using the transducers, image resolutions are higher and advances can be made to 4D ultrasound.

The company also designs and manufactures complete transducers, working closely with electrical engineers and original equipment manufacturers to design high-performance systems.

The new piezoceramic is used to make 1-3 transducer and 2-2 transducer plates, which give high performance in frequencies ranging from 200KHz to 4MHz.

Finely pitched composite configurations act with lower acoustic impedance than traditional monolithic components.

The piezoceramic material is arranged in pillars with a polymer matrix filler.

By combining the materials in this way, the overall density of the composite structure better matches the medium of the material the sound waves travel through.

The lower acoustic impedance allows a higher energy transfer through body tissue or water, resulting in a lower reverberation level on the front face of the acoustic device.

Piezocomposite materials benefit from a damping effect of the polymer, which reduces lateral vibration modes, cross coupling and spurious activity, resulting in improved transducer bandwidth.

The piezoceramic composite eliminates interference that a conventional monolithic transducer would exhibit, thus improving transmission efficiency and reception sensitivity, said the company.

Morgan Technical Ceramics offers piezoceramic custom composites in 1-3 and 2-2 architectures, in sizes up to 40mm square and in many shapes, including cylindrical, spherical and curved.

In addition, the company offers complete transducers based on piezoceramic composite technology.

In-house underwater acoustic test tanks and pressure testing facilities are used to validate the performance of different designs.

This integration of all process steps enables the company to develop custom solutions with short lead times.

Transducers can be designed with appropriate matching layers, encapsulation and cables, suitable for the harsh conditions found in marine environments, and manufactured in volume for many medical and industrial applications.
