Capacitive Micromachined Ultrasonic Transducers for Non-destructive Testing Applications
Wong, Lawrence (University of Waterloo, 2014-08-07)Ultrasound is a popular technique for industrial non-destructive testing (NDT) applications. By sending ultrasonic waves into an object and observing the amplitude and the delay of the reflected or transmitted waves, one ... -
A novel deflection shape function for rectangular capacitive micromachined ultrasonic transducer diaphragms
Yeow, John; Sun, Zhendong; Wong, Lawrence; Suo, Xudong; Sun, Weijie; Zheng, Zhou (Elsevier, 2015-07-15)A highly accurate analytical deflection shape function that describes the deflection profiles of capacitive micromachined ultrasonic transducers (CMUTs) with rectangular membranes under electrostatic pressure has been ...
