Abstract
A downhole transducer can include at least one single-crystal piezoelectric material, the at least one single-crystal piezoelectric material being positioned in the downhole transducer that is deployed downhole in a wellbore. Additionally, the downhole transducer can include at least one pair of electrodes positioned adjacent to the at least one single-crystal piezoelectric material for determining wellbore parameter measurements using one or more acoustic signals transmitted in the wellbore. The single-crystal piezoelectric material can include PIN-PZN-PT.

A downhole transducer comprising:
- at least one single-crystal piezoelectric material that includes PIN-PZN-PT, the at least one single-crystal piezoelectric material positionable in the downhole transducer that is deployable downhole in a wellbore;
- and
- at least one pair of electrodes positionable adjacent to the at least one single-crystal piezoelectric material for determining one or more wellbore parameter measurements using one or more acoustic signals transmittable in the wellbore.
A system comprising:
- a downhole tool positionable in a wellbore;
- and
- a downhole transducer positionable in the downhole tool, the downhole transducer comprising:
- at least one single-crystal piezoelectric material for determining one or more wellbore parameter measurements using one or more acoustic signals transmittable in the wellbore, the single-crystal piezoelectric material including PIN-PZN-PT;
- and
- at least one pair of electrodes positionable adjacent to the at least one single-crystal piezoelectric material.
A method comprising:
- receiving, via a downhole transducer deployed in a wellbore, one or more acoustic signals, the downhole transducer comprising (i) at least one single-crystal piezoelectric material for determining one or more wellbore parameter measurements using the one or more acoustic signals and (ii) at least one pair of electrodes positioned adjacent to the at least one single-crystal piezoelectric material, the at least one single-crystal piezoelectric material positioned in the downhole transducer and including PIN-PZN-PT;
- and
- determining, via a sensing system, the one or more wellbore parameter measurements based on an output provided by the downhole transducer.
