Abstract

Capacitive micromachined ultrasonic transducers (CMUTs) have emerged as a promising technology in the field of ultrasonic biomedical applications due to their unique advantages over traditional piezoelectric transducers. This presentation explores the fundamental principles, design, and fabrication of CMUTs, highlighting their potential to revolutionize diagnostic and therapeutic procedures in medicine.

CMUTs offer superior bandwidth, better integration with electronic circuits, and higher sensitivity, making them ideal for applications such as high-resolution imaging, blood flow measurement, and tissue characterization. Additionally, their fabrication using standard silicon semiconductor manufacturing processes facilitates miniaturization and the development of advanced multi-element arrays with stretchability, wearability and disposability, enhancing the capabilities of ultrasound systems.

We will discuss the various biomedical applications of CMUTs, including their use in diagnostic and therapeutic applications. By examining the potential and challenges of CMUTs in biomedical applications, this presentation aims to provide insights into the future directions of ultrasonic technologies in healthcare, paving the way for more accurate, cost-effective, and non-invasive medical tools.
