Piezoelectric ceramic for low frequency hydrophones
Yuhai's piezoelectric block has been utilized continuously in low frequency hydrophones in more than 30 years.
A hydrophone (Ancient Greek ὕδωρ = water and φωνή = sound) is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a Piezoelectric Transducer that generates an electric potential when subjected to a pressure change, such as a sound wave.
