Abstract
A hydrophone may include a first piezoelectric cable including alternating sections of positive polarity and negative polarity, and a second piezoelectric cable including alternating sections of negative polarity and positive polarity. At least a portion of each section of positive polarity of the first piezoelectric cable may be bonded or adhered to at least a portion of a section of negative polarity of the second piezoelectric cable. A method of manufacturing a hydrophone may include winding or coiling a first piezoelectric cable and a second piezoelectric cable at the same time to create a series of wound sections including cables, the wound sections alternating with a series of not wound sections including the cables.

A hydrophone comprising:
- a first piezoelectric cable comprising alternating sections of positive polarity and negative polarity;
- and
- a second piezoelectric cable comprising alternating sections of negative polarity and positive polarity, where at least a portion of each section of positive polarity of the first piezoelectric cable is bonded to at least a portion of a section of negative polarity of the second piezoelectric cable;
- wherein the first piezoelectric cable comprises an inner conductor and a continuous layer of piezoelectric material coating and the second piezoelectric cable comprises an inner conductor and a continuous layer of piezoelectric material coating.
