Ultrasound transducers are regularly used in medical clinics but their performance is known to deteriorate over time. Causes of this image quality degradation can include delamination between layers, physical breakage of components, short circuits and weakening crystals. Regular ... Per saperne di più
In order to exploit the piezotronic effect of Zinc Oxide (ZnO) crystal and to design an optimal high gauge strain sensors. One would require a deep understanding of the dynamics of charge carrier transport and accurately predict the levels of mechanical stress field and electrical charge ... Per saperne di più
Many industrial applications require special treatments for fluid products, such as: deagglomeration, dispersion, homogenization, emulsion, special mixing or even catalysis of chemical reactions. Such effects can be obtained through cavitation in a closed ultrasonic reactor, in which it ... Per saperne di più
Interacting with digital devices has become part of daily life, whether in consumer products, services, or industrial applications. Most display-based devices provide user interactivity through touch sensing via a touch panel. As the number of device features increases, it demands an ... Per saperne di più
Fouling accumulation in pipelines is a known problem in industry which is currently treated by mechanical, hydraulic and chemical means. Each requiring a halt in the production to carry out the procedure. Industry requires a method that is non-invasive and can be used in-situ, Ultrasonic ... Per saperne di più
In our work, simulations of a piezoelectrical micromachined ultrasonic transducer compatible with CMOS-MEMS process are presented. The piezoelectric material of the PMUT is AlN sandwiched between two Al layers and a top Si3N4 passive layer. The piezoelectric and the metal materials have ... Per saperne di più
SAW devices, in which acoustic wave travels along the surface of a material, are used as filters, oscillators and delay lines in electronic circuits. However, recent research [1] revealed that bulk acoustic waves (BAW) can be nonlinearly generated in LiNO3 SAW device if the drive level ... Per saperne di più
This paper proposes a solution method using piezoelectric sensors to detect an anomaly, such as a deformation caused by a crack or fracture, in a pipeline. COMSOL Multiphysics, a simulation software, is used to induce anomalies of different magnitudes to a pipe and record the data from ... Per saperne di più
The five year survival rate for malignant brain and central nervous system cancer was estimated at 35% between 2000 and 2015. Deep brain tumors can be unsuited for conventional surgical intervention. One minimally invasive treatment option is interstitial needle-based therapeutic ... Per saperne di più
生物医疗电子产品成为当前发展的新热点，为了与人体表面皮肤贴合，各种柔性材料用于制备医疗检测器件。其中，PVDF材料拥有良好的柔性、压电性、压阻性和生物相容性，可制备适用于符合人体力学的柔性探测器。PVDF材料具有很大的压电电压常数，微小的形变能产生较大的电势差。利用此特性，可检测颈椎、腰椎和膝关节的运动状况，极大的避免造成人体损伤。 利用Comsol多物理场有限元仿真软件，构建PVDF柔性器件结构，设置驱动材料和电极材料相关参数参数，选取固体力学模块和AC/DC模块，网格化分析求解，量化PVDF柔性器件形变和电压的关系。 comsol有限元分析软件具有多个专业模块 ...
