Water calorimetry is employed to establish a primary reference standard for radiation dosimetry by measuring the temperature rises in a water phantom (a cube of about 30 cm x 30 cm x 30 cm) subjected to a beam of ionizing radiation. We use COMSOL Multiphysics to model the system using ... Read More
In this paper we present a method to mitigate the effect of thermally-induced noise in Micro-Electro-Mechanical Systems (MEMS) through a force feedback circuit. Inherent noise-induced vibrations, which would be inconsiderable in macro scale, are considered as a limitation in micro- and ... Read More
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 ... Read More
生物组织的生理和病理结构发生变化时, 导致组织电导率发生变化。因此,通过检测组织电导率来及时发现组织结构生理和病理情况,可以为癌症早期诊断提供依据。磁声电成像(MAET)是一种新颖的医学成像方法,由于在成像过程中使用了超声激励和电阻抗电极检测,所以其图像具有超声成像的高分辨率和电阻抗成像的高对比度。本研究使用的接口有压力声学时域显式和电流,仿真中使用2 MHz,2个cycle的正弦脉冲驱动聚焦超声探头,求解时域显式压力声学方程,获得组织振动速度。然后在电流接口中设置外部电流密度,把速度洛伦兹项耦合进外部电流密度,使用接地和浮电势检测电极上采集的磁声电电压 ... Read More

Usually fatigue-life tests of materials are long, time-consuming and expensive. With the development of high power piezoceramic actuators nowadays it is possible to provide at very high cycles 10e10 fatigue tests (VHCF) for reasonable times, at high frequency. The ultrasonic fatigue ... Read More
The purpose of this paper is to describe numerical electro-thermal simulations of the REMS wind sensor unit and the results obtained by using COMSOL Multiphysics. This device is a hot-film anemometer for 2D wind measurements, which does not have movable parts and is based on the air ... Read More
In this paper, we present study on the mass loading effect of the interdigital transducer (IDT) on surface acoustic wave (SAW) velocity in SAW devices, using COMSOL Multiphysics. We have simulated a one port SAW resonator made on YZ lithium niobate substrate and investigated the ... Read More
Introduction Leaky Surface Acoustic Wave (LSAW) resonators in rotated Y-X cut Lithium Tantalate (LiTaO3) are widely used for resonator based ladder filters in telecommunication applications. These devices make use of quasi- shear waves confined to the surface of the piezoelectric layer ... Read More
The self heating process of Tetrafluoroethylene caused by an exothermic dimerization reaction was studied. The heat of reaction can lead to a thermal explosion by the decomposition of the Tetrafluoroethylene. Different reaction kinetics, including multistep kinetics, were used to ... Read More
