Fabrication and characterization of surface micromachined capacitive ultrasonic immersion transducers
TL;DR: In this paper, several innovative steps used in fabricating surface micromachined capacitive ultrasonic immersion transducers are reported, such as membrane formation, vacuum sealing, and electrode metallization.
Journal ArticleDOI
Characterization of one-dimensional capacitive micromachined ultrasonic immersion transducer arrays
TL;DR: Several methods, such as trench isolation and wafer thinning, are proposed and implemented to modify the acoustical cross coupling between array elements.
Journal ArticleDOI
Annular-ring CMUT arrays for forward-looking IVUS: transducer characterization and imaging
TL;DR: It is demonstrated that annular-ring CMUT arrays fabricated with CMOS-compatible processes are capable of forward-looking IVUS imaging, and the developed modeling tools can be used to design improved IVUS Imaging arrays.
Journal ArticleDOI
Phononic crystal Luneburg lens for omnidirectional elastic wave focusing and energy harvesting
TL;DR: In this article, a phononic crystal Luneburg lens was constructed using hexagonal unit cells with blind holes of different diameters, which were determined by finite element simulations of the lowest asymmetric mode Lamb wave band structure.
Journal ArticleDOI
Front-end receiver electronics for high-frequency monolithic CMUT-on-CMOS imaging arrays
TL;DR: This paper describes the design of CMOS receiver electronics for monolithic integration with capacitive micromachined ultrasonic transducer (CMUT) arrays for high-frequency intravascular ultrasound imaging and shows successful system operation with a pulseecho measurement.
