3Beyond fundamental resonance mode:high-order multi-band ALN PMUT for in vivo photoacoustic imaging显示文摘This paper reports on an aluminum nitride(AlN)piezoelectric micromachined ultrasound transducer(PMUT)array for photoacoustic(PA)imaging,where the high-order resonance modes of the PMUT are utilized to improve imaging resolution.A flexural vibration mode(FVM)PMUT is fabricated and applied in a photoacoustic imaging(PAI)system.Specifically,the microelectromechanical system(MEMS)-based PMUT is suitable for PA endoscopic imaging of blood vessels and bronchi due to its miniature size and high sensitivity.More importantly,AlN is a nontoxic material,which makes it harmless for biomedical applications.In the PAI system,the AlN PMUT array is used to detect PA signals,and the acousto–mechanical response is designed and optimized at the PMUT’s fundamental resonance.In this work,we focus on the high-order resonance performance of the PMUT PAI beyond the fundamental resonance.The acoustic and electrical responses of the PMUT’s high-order resonance modes are characterized and analyzed.The fundamental and three high-order resonance bandwidths are 2.2,8.8,18.5,and 48.2 kHz.Compared with the resolution at the fundamental resonance mode,the resolutions at third-and fourth-order resonance modes increase by 38.7%and 76.9%in a phantom experiment.The high-order resonance modes of the AlN PMUT sensor array provide higher central frequency and wider bandwidth for PA signal detection,which increase the resolution of PAI compared to the PMUT working at the fundamental resonance mode.Junxiang Cai Yiyun Wang Daohuai Jiang Songsong Zhang Yuandong Alex Gu Liang Lou Fei Gao Tao Wu 2022Microsystems & Nanoengineering2022,8,6:1

9GASTROINTESTINAL ABNORMALITIES IDENTIFIED BY FLUORESCENCE ENDOMICROSCOPY显示文摘Real-tine in vivo microscopic imaging has becomne a reality with the advent of confocal and nonlinear endomicroscopy.These devices are best utilized in conjunction with standard white light endoscopy.We evaluated the use of fuorescence endomicroscopy in detecting microscopic abnormalities in colonic tisues.Mice of C57bl/6 strain had intraperitoneal injection with azoxymethane once every week for five weeks and littermates,not exposed to azoxymethane served as controls.After 14 weeks,intestines were imaged by fuorescence endomicroscopy.The images show obvious cellular structural diferences between those two groups of mice.The difference in endomicroscopy imaging can be used for identifying tissues suspicious for neoplasia or other changes,leading to early diagnosis of gastrointestinal track of cancer.HONGCHUN BAO ALEX BOUSSIOUTAS MCGEAREY ALEIXANDRIA RITA BUSUTTIL MIN GU 2012Journal of Innovative Optical Health Sciences2012,5,4:0

11Flexible thin-film acoustic wave devices with off-axis bending characteristics for multisensing applications显示文摘Flexible surface acoustic wave(SAW)devices have recently attracted tremendous attention for their widespread application in sensing and microfluidics.However,for these applications,SAW devices often need to be bent into offaxis deformations between the acoustic wave propagation direction and bending direction.Currently,there are few studies on this topic,and the bending mechanisms during off-axis bending deformations have remained unexplored for multisensing applications.Herein,we fabricated aluminum nitride(AlN)flexible SAW devices by using high-quality AlN films deposited on flexible glass substrates and systematically investigated their complex deformation behaviors.A theoretical model was first developed using coupling wave equations and the boundary condition method to analyze the characteristics of the device with bending and off-axis deformation under elastic strains.The relationships between the frequency shifts of the SAW device and the bending strain and off-axis angle were obtained,and the results were identical to those from the theoretical calculations.Finally,we performed proof-of-concept demonstrations of its multisensing potential by monitoring human wrist movements at various off-axis angles and detecting UV light intensities on a curved surface,thus paving the way for the application of versatile flexible electronics.Zhangbin Ji Jian Zhou Huamao Lin Jianhui Wu Dinghong Zhang Sean Garner Alex Gu Shurong Dong YongQing Fu Huigao Duan 2021Microsystems & Nanoengineering2021,7,6:0
12Strategy to minimize bending strain interference for flexible acoustic wave sensing platform显示文摘There are great concerns for sensing using flexible acoustic wave sensors and lab-on-a-chip,as mechanical strains will dramatically change the sensing signals(e.g.,frequency)when they are bent during measurements.These strain-induced signal changes cannot be easily separated from those of real sensing signals(e.g.,humidity,ultraviolet,or gas/biological molecules).Herein,we proposed a new strategy to minimize/eliminate the effects of mechanical bending strains by optimizing off-axis angles between the direction of bending deformation and propagation of acoustic waves on curved surfaces of layered piezoelectric film/flexible glass structure.This strategy has theoretically been proved by optimization of bending designs of off-axis angles and acoustically elastic effect.Proof-of-concept for humidity and ultraviolet-light sensing using flexible SAW devices with negligible interferences are achieved within a wide range of bending strains.This work provides the best solution for achieving high-performance flexible acoustic wave sensors under deformed/bending conditions.Jian Zhou Zhangbin Ji Yihao Guo Yanghui Liu Fengling Zhuo Yuanjin Zheng Yuandong(Alex)Gu YongQing Fu Huigao Duan 2022npj Flexible Electronics2022,6,1:0
