Journal ArticleDOI
Piezoelectric Micromachined Ultrasound Transducer (PMUT) Arrays for Integrated Sensing, Actuation and Imaging
Yongqiang Qiu,James Gigliotti,Margeaux Wallace,Flavio Griggio,Christine E. M. Demore,Sandy Cochran,Susan Trolier-McKinstry +6 more
TL;DR: An overview of the current development status of piezoelectric micromachined ultrasound transducers and a discussion of their suitability for miniaturized and integrated devices are presented.
Journal ArticleDOI
Substrate clamping effects on irreversible domain wall dynamics in lead zirconate titanate thin films.
Flavio Griggio,Stephen Jesse,Amit Kumar,Oleg S. Ovchinnikov,Hyung Kook Kim,Thomas N. Jackson,Dragan Damjanovic,Sergei V. Kalinin,Susan Trolier-McKinstry +8 more
TL;DR: It is demonstrated that measurements on clamped films may considerably underestimate the piezoelectric coefficients and coupling constants of released structures used in microelectromechanical systems, energy harvesting systems, and microrobots.
Journal ArticleDOI
Kinetic Studies of Mullite Synthesis from Alumina Nanoparticles and a Preceramic Polymer
TL;DR: In this paper, the crystallization kinetics of mullite formation in a diphasic precursor consisting of a silicone resin filled with commercial γ-alumina nanoparticles (15 nm mean particle size, specific surface area of 100 m2/g), heated in air from 1250° to 1350°C, was studied by X-ray diffraction.
Journal ArticleDOI
CMOS Ultrasound Transceiver Chip for High-Resolution Ultrasonic Imaging Systems
Insoo Kim,Hyunsoo Kim,Flavio Griggio,R.L. Tutwiler,Thomas N. Jackson,Susan Trolier-McKinstry,Kyusun Choi +6 more
TL;DR: The proposed CMOS ultrasound transceiver chip will enable the development of portable high resolution, high-frequency ultrasonic imaging systems and is designed for close-coupled MEMS transducer arrays which operate with a 3.3-V power supply.
Journal ArticleDOI
Designing piezoelectric films for micro electromechanical systems
Susan Trolier-McKinstry,Flavio Griggio,C. Yaeger,Pierre Jousse,Dalong Zhao,S. S. N. Bharadwaja,Thomas N. Jackson,Stephen Jesse,Sergei V. Kalinin,Kiyotaka Wasa +9 more
TL;DR: It was found that chemical solution-derived PbZr0.52Ti0.48O3 thin films show clusters of larger nonlinear response embedded in a more weakly nonlinear matrix, suggesting that collective motion of many domain walls contributes to the observed Rayleigh behavior in these films.
