A finite element model of a total hip replacement (THR) has been developed from the approach of modal analysis. The model is capable of determining the first 15 Eigenmodes of a THR with an artificial bone model. The model was equipped with several different defects to simulate a ... Read More
This paper aims to demonstrate the simulation of photoacoustic signals using FEM software. The Acoustics Module of the software COMSOL Multiphysics is used to calculate the response of a differential Helmholtz resonator cell. In a second part a preliminary result obtained with the ... Read More
One of the most promising categories of semiconductor-based sensors is organic electrochemical transistor (OECT), which consists of three electrodes (Source, Drain and Gate) and two active layers: electrolyte and conductive polymer. Despite the fact that OECT attracts a lot of attention ... Read More
Pressure-driven air flow is directed over the microfluidic cavity induces circulating fluid motion in the cavity. Analyte contained in the air stream is absorbed into the cavity, mixes with the nanoparticles as a result of the circulating cavity flow. Therefore, the nanoparticles ... Read More
Piezo buzzers, made of piezoelectric material glued on a brass plate, are usually used as signaler, but the buzzer can also be used to convert mechanical into electrical energy. If acceleration influences the buzzer, the structure is bent by its mass and a voltage can be measured between ... Read More
This paper presents numerical simulation of plate wave modes in thin stainless steel plates using a racetrack spiral coil electromagnetic acoustic transducer (EMAT), which works under the principle of acousto-elastic effect, called Lorentz force mechanism. EMATs are useful for non ... Read More
Due to the increasing demand for hydrogen gas sensors for applications such as automation, transportation, or environmental monitoring, the need for sensitive and reliable sensors with a short response time is increasing. This paper presents an empirical model that studies the ... Read More

引言： 对于微流控分选芯片而言，分支出口的位置、宽度等几何参数会直接影响到粒子分选精度与回收效率。但是，遗憾的是，对于流道各分支出口位置的高效设计方法却鲜有报道。当前的设计方法主要是对每一种目标粒子直接进行轨迹仿真[1~7]。但这种方法的运算成本巨大，如果粒子分散体系涉及到的粒径种类繁多且流道结构复杂，那么对每种粒径都进行仿真分析将会使得计算量与计算精度之间的矛盾愈加尖锐；而且，每引入一种没有被仿真研究过的粒径，都要对其重新进行仿真运算，运算成本巨大[8~10]。 据此，本文提出了一种结合有限元分析仿真与系统辨识方法的粒子出射位置预测方法 ... Read More
