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 ... Per saperne di più
This communication reports on a numeric fluid dynamics simulation on a pipe flow model. The basic background is to determine the velocity of a flowing fluid in a pipe by using the Thermal Time-Of-Flight (TTOF) method on water. The visualization of the temperature and velocity ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
Strain gauges have been extensively used for detecting strain in various applications. Double-ended tuning fork (DETF) strain gages present better performance characteristics than standard foil gauges, including higher sensitivity, smaller size and higher resolution. This study focuses ... Per saperne di più
There is a practical interest among composite materials manufacturers to high-speed accurate non-destructive evaluation (NDE) technology for voids inspection when these voids are natural components of such complex structures like resin insulated layer of double-sided copper-clad ...

A continuous flow polymerase chain reaction with integrated MEMS based design micro heater for DNA amplification is implemented. Temperature ... Per saperne di più
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 ... Per saperne di più
