A Piezoelectric Polymer Hydrophone.
Abstract
One object of the invention is to provide a shock resistant hydrophone. Another object of the invention is to provide a hydrophone using a piezoelectric sensor element with a density approximating that of water. Yet a further object of this invention is to provide a hydrophone capable of broadband, high frequency operation. The invention is a hydrophone using a piezoelectric polymer such as polyvinylidene fluoride as the sensing element. The piezoelectric polymer is formed into a thin wall tube with deposited electrodes on the interior and exterior surfaces. An elastomer core fills the interior of the tube and provides radial compression against the interior of the tube.
