The Open-Circuit Sensitivity of Axially Polarized Ferroelectric Ceramic Cylinders
Abstract
The open-circuit sensitivities of axially polarized ferroelectric ceramic cylinders are derived by treating the ceramic as an anisotropic material. Although the results for cylinders that are pressure-released at the inside lateral surface were identical to those given by Langevin, the analysis showed that the anisotropic properties of currently used ceramics did not influence the sensitivities of these types of cylindrical hydrophone elements. Axially poled cylinders that were completely pressure-released with respect to the radial coordinate were found to exhibit sensitivities larger than those of similar cylinders that were pressure-released on only one major surface, the inside lateral surface. Included in this report are graphs of the magnitude of the stresses induced in the cylinders by the ambient hydrostattic pressures.
