Suitability of piezoelectric materials in water

Click For Summary
SUMMARY

Piezoelectric materials can function in constant contact with water when embedded in waterproof materials that facilitate sound wave transmission. This method is commonly used in transducers for depth finders and fish finders. The longevity of these materials in aquatic environments depends on the specific waterproofing techniques employed. Concerns regarding water pollution from these materials are generally mitigated by the protective coatings used.

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.
