Piezo elements are used in military and commercial sonar systems for position finding activities. Location of fish and surface/subsurface vessels, depth measurement, surveying, and communication are several of the more common sonar applications. Piezoelectric ceramic materials have high bandwidth and can quickly respond by applying high force at low power levels. These materials are generally unaffected by environmental factors such as humidity and temperature. Our materials sustain high levels of drive voltage and provide excellent coupling factors in sonar applications while possessing the capability to form to customer specifications and availability in a wide range of geometries with dimensions up to 150 mm or thicknesses less than 100 microns.
CTS recommends material types K1000 and K1300 for sonar applications.
