  • ULTRASONIC TRANSDUCER
    Publication number: 20230302496
    Abstract: There are provided an ultrasonic transducer and methods for designing and manufacturing the same. The ultrasonic transducer includes a piezoelectric composite layer configured to be in acoustic communication with a sample and having at least partially decoupled acoustic impedance and electrical impedance properties. The piezoelectric composite layer includes an array of spaced-apart piezoelectric regions, each being made from a piezoelectric material, a filler material positioned between adjacent spaced-apart piezoelectric regions, the filler material comprising a polymer matrix and a non-piezoelectric material in contact with the polymer matrix.
    Type: Application
    Filed: June 2, 2023
    Publication date: September 28, 2023
    Applicant: RESONANT ACOUSTICS INTERNATIONAL INC.
    Inventors: Nicholas Chris Chaggares, Eric M. Rieder, Khachic Karshafian
