Hydrophone  Applications:


Piezoelectric material is ideal for making hydrophones. They can change their form and help generate an electrical potential in response to mechanical or external pressure changes. When an electrical voltage is applied to the crystalline ceramic material, the crystalline structure aligns, becomes anisotropic, and carries an electrical charge.

A typical hydrophone has a transducer. This transducer is crucial for converting the incoming sound waves into an electrical voltage. Use of a piezoelectric transducer as an alternative to crystal material is now a popular option in modern-day hydrophone technology.
