FEM-based analysis on sensing out-of-plane displacements of low-order Lamb wave modes by CMUTs

Lu, W.; Zhang, S.; Wang, R.; Yang, Y.; Zhang, G.; Zhang, W.; Xu, B.; Yılmaz, Mehmet (AIP Publishing LLC, 2022-11-23)

It is well known that acoustic emission (AE) signals, generated by external impacts or damages such as crack initiation, mainly propagate in the form of Lamb waves in plate-like structures. In this work, MEMS-based resonant ...
Theoretical and simulation studies on designing a phase-reversal-based broadband CMUT with flat passband and improved noise rejections for SHM

Lu, W.; Zhang, S.; Wang, R.; Xu, B.; Yılmaz, Mehmet; Zhang, W. (Institute of Electrical and Electronics Engineers, 2022-11-15)

In the past two decades, capacitive micromachined ultrasonic transducers (CMUTs) have been greatly explored for applications in structural health monitoring (SHM); however, relevant theories about their broadband sense ...
