Pzt hydrophone
WebA shear-polarized hydrophone was fabricated by using 0—3PZT/P(VDF-TFE) piezocomposite. According to the theoretical analysis, the theoretical sensitivity was acquired. Compared with the theoretical sensitivity, a sample with higher sensitivity up to –190.2 dB ref. 1V/μPa was developed. The theoretic research and experimental results … WebJun 1, 2007 · The net hydrostatic response of a block of piezoelectric PZT is roughly negated [10, 11] by the equal but opposite contributions from d 33 and (d 13 + d 23).Thus solid blocks or PZT have a relatively poor d h values. A hydrophone transducer is employed as a sensor, and its sensitivity is determined by the voltage produced in response to a …
