Combination motion and acoustic piezoelectric sensor apparatus and method of use therefor
First Claim
1. An apparatus, comprising:
- a seismic streamer;
a housing section of said seismic streamer;
an acoustic sensor comprising;
a first and a second thin film piezopolymer;
a flexible microsphere loaded transfer adhesive wherein said microsphere loaded transfer adhesive proximately contacts said first thin film piezopolymer, a zone of non-microsphere loaded transfer adhesive proximately contacting said second thin film piezopolymer; and
a motion sensor, said acoustic sensor and said motion sensor co-located in said housing.

Abstract
Sensors used in mapping strata beneath a marine body are described, such as used in a flexible towed array. A first sensor is a motion sensor including a conductive liquid in a chamber between a rigid tube and a piezoelectric motion film circumferentially wrapped about the tube. A second sensor is a traditional acoustic sensor or a novel acoustic sensor using a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Additional non-acoustic sensors are optionally mounted on the rigid substrate for generation of output used to reduce noise observed by the acoustic sensors. Combinations of acoustic, non-acoustic, and motion sensors co-located in rigid streamer housing sections are provided.
