Piezoelectric composite components
Morgan Advanced Materials, a leading manufacturer of electro ceramic products, including piezoelectric ceramics, high voltage and RF capacitors and microwave ceramics, announced the launch of a new range of piezoelectric composite components, ideal for applications where high performance is critical, including medical imaging, Doppler flow, and military and commercial sonar. Components manufactured with Piezo composite materials offer improved acoustic performance over traditional transducer materials, feature higher transmit and receive efficiency, and can be produced in custom sizes, shapes, and materials.
Morgan’s piezoelectric composite materials drastically reduce the cross-coupling that typically occurs between different modes in the ceramic of conventional transducers, enabling medical components to respond in a more precise and predictable manner. Components manufactured by Morgan also reduce spurious activity,resulting in higher transmit and receive efficiency. These Piezo composite components also provide lower acoustic impedance and improved transducer bandwidth than conventional piezoelectric ceramics.
Morgan offers piezoelectric composites in both 1-3 and 2-2 orientations, in sizes up to 3-inch square and frequencies from 100 kHz to 12 MHz. To enhance transmit and receive response rates, piezoelectric volume fractions can be tailored for any application.
The Piezo composites can be thermoformed to conform to curved, complex geometric surfaces in shapes often not achievable with conventional piezoceramic materials, significantly increasing design flexibility. Morgan’s extensive materials portfolio allows further flexibility as components can be manufactured from standard or custom materials, including Navy types I, II, and VI.
