Presentation title: MEMS-based underwater acoustics sensor design approaches
Abstract: This talk delves into the innovative design approaches for MEMS-based Underwater Acoustic Sensors, focusing on Capacitive Micromachined Ultrasonic Transducers (CMUT) and Piezoelectric Micromachined Ultrasonic Transducers (PMUT). CMUT employs electrostatic forces to transmit and receive ultrasonic waves, offering advantages such as high sensitivity, low power consumption, and broad bandwidth. Conversely, PMUT utilizes piezoelectric materials for wave generation and detection, promising robust performance in harsh underwater environments. The discussion will cover the fundamental principles, fabrication techniques, and performance characteristics of both CMUT and PMUT designs. Furthermore, it will explore their applications in underwater communication, navigation, and surveillance systems. By comparing and contrasting these two MEMS technologies, this talk aims to provide insights into their respective strengths and limitations, guiding the audience in selecting the most suitable approach for diverse underwater sensing requirements. |
