Patent 10280744 was granted and assigned to Halliburton on May, 2019 by the United States Patent and Trademark Office.
An acoustic transducer, such as a bender bar, having ferroelectric actuation elements that are designed to optimize a predetermined deflection mode shape.

Modal shaping of the actuation elements allows for specific targeting of modes which most efficiently radiate acoustic energy.
