Hydrophone basics

Zhang et al. [83,84] have shown theoretically that the basic elastic coupling mechanism between the two componeata b the 2>2 piezoelectric composite is similar to that of the 1-3 composite, although the 2-2 structure b not widely us There ate two major areas where 1-3 composites have been widely used underwater hydrophone applications and ultrasonic actuators and sensors for medical dUgnostk devices [15,16,24,8334].
