PZT Hollow Sphere Transducers
Abstract
Hollow sphere transducers 1 cm and larger made from PZT have been manufactured commercially for many years. The F-22 series of Navy hydrophones is typical. The spheres possess a stress amplification factor which imparts great sensitivity to the design while at the same time providing acceptable pressure tolerance, In this study we have made spheres in sizes down into the millimeter range while retaining the same amplification factor and pressure tolerance characteristic of large hollow spheres. Our aim is to develop miniature hydrophones for studying flow noise, and for making shallow water arrays.
