The components offer improved acoustic performance over traditional transducer materials, claims the manufacturer, with higher transmit and receive efficiency, and can be produced in custom sizes, shapes, and materials.
These 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. These Piezo composite components also provide lower acoustic impedance and improved transducer bandwidth than conventional piezoelectric ceramics. The new piezoelectric composites are available 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.
