Surface micromachined capacitive ultrasonic transducers [PDF]

open access: yesIEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1998
The current state of novel technology, surface microfabricated ultrasonic transducers, is reported. Experiments demonstrating both air and water transmission are presented. Air-coupled longitudinal wave transmission through aluminum is demonstrated, implying a 110 dB dynamic range for transducers at 2.3 MHz in air. Water transmission experiments from 1
