Suitability of piezoelectric materials in water

AI Thread Summary
Piezoelectric materials can function in constant contact with water when embedded in waterproof casings that permit sound wave transmission. These materials are commonly used in transducers for applications like depth finders and fish finders. The expected lifetime of piezoelectric devices in water varies based on the specific material and environmental conditions. Concerns about pollution depend on the type of piezoelectric material used, as some may leach substances into the water over time. Overall, careful selection and design can mitigate potential issues while maintaining functionality.

The title pretty much says it all.
I want to know if any piezoelectric materials can fully function in constant contact with water. If so, how long a lifetime could be expected and would there be any polluting to the water?

Thanks

The piezoelectric material is usually embedded in waterproof material that allows the sound waves to pass to and from the water.

This is how it in done in transducers for depth finders and fish finders.
