    Area of Science:

    • Materials Science
    • Acoustics Engineering
    • Mechanical Engineering

    Background:

    • Piezoelectric micromachined ultrasonic transducers (PMUTs) are crucial for ultrasonic signal applications.
    • Conventional PMUT designs can exhibit narrow bandwidths, limiting their performance.
    • Miniaturization and low power requirements make PMUTs suitable for integration.

    Purpose of the Study:

    • To enhance the bandwidth of air-coupled PMUTs without compromising sensitivity.
    • To present a novel transducer design inspired by pipe organ acoustics.
    • To demonstrate the effectiveness of the proposed methodology through a prototype.

    Main Methods:

    • Designing a novel transducer with a backplate inspired by a pipe organ.
    • Fabricating the prototype using additive manufacturing (3-D printing).

  • Utilizing a polyvinylidene fluoride thin film and a stereolithography-designed backplate.

    • Main Results:

    • The developed "pipe organ" air-coupled transducer achieved a -6-dB bandwidth of 55.7% (transmitting) and 58.5% (receiving).
    • This bandwidth is approximately 5 times wider than a standard custom-built device.
    • The design successfully improved bandwidth without sensitivity loss.

    Conclusions:

    • The pipe organ-inspired design is an effective method for enhancing PMUT bandwidth.
    • Additive manufacturing enables the fabrication of complex transducer structures.
    • This advancement holds promise for industrial and biomedical ultrasonic applications.
