Piezo is a critical element in producing hydrophones for military and commercial underwater listening applications. Hydrophones utilize piezoelectric elements to detect sound pressure waves produced by underwater vessels, animals, and the environment. Hydrophones must have a flat frequency response that is proportional to the magnitude of the sound pressure wave. Our materials have excellent electric properties, enabling piezoelectric elements to provide excellent frequency responses and necessary high coupling factors to form to the desired mechanical structure for hydrophones.
We recommend material types K1300, 3195, and 3203 for hydrophone applications.
