    Area of Science:

    • Acoustics
    • Materials Science
    • Sensor Technology

    Background:

    • Miniature microphones for ultrasonic measurements above 100 kHz are often expensive, lack sensitivity, or are too large.
    • Existing solutions do not meet the requirements for precise ultrasonic wave field scans in air.

    Purpose of the Study:

    • To develop a miniature, sensitive, and cost-effective ultrasonic microphone using ferroelectret (FE) film.
    • To evaluate the performance of the novel FE microphone for ultrasonic measurements.

    Main Methods:

    • Constructed a 0.5-mm-diameter needle-style ultrasonic microphone utilizing FE film.
    • Evaluated performance through sensitivity area mapping using laser-induced thermoelastic ultrasound, directivity, AC response, and absolute sensitivity calibration via three-transducer reciprocity.
    • Compared FE microphone performance with a polyvinylidene difluoride (PVDF) microphone.

    Main Results:

    • The FE microphone demonstrated high sensitivity and a broad frequency range suitable for ultrasonic measurements.
    • Sensitivity map revealed micrometer-scale granularity of the FE material.
    • Laser-based methods provided reliable AC response measurements, validated by reciprocity calibration.

    Conclusions:

    • Ferroelectret film is a promising material for constructing miniature, high-performance ultrasonic microphones.
    • The developed FE microphone offers a cost-effective and sensitive alternative for ultrasonic field measurements.
    • Novel laser-based characterization techniques were successfully employed for microphone evaluation.
