The Laser Direct Synthesis and Patterning (LDSP) technology has advantages in terms of processing time and cost compared to nanomaterials-based laser additive microfabrication processes. In LDSP, a scanning laser on the substrate surface induces chemical reactions in the reactive liquid solution and selectively deposits target material in a preselected pattern on the substrate. In this study, w...

Engineering education in fluidics means to convey the physical principles behind pneumatic or hydraulic building blocks such as valves or cylinders. Up to now fluidic hardware plays an important role in this connection: Education laboratories with semi-professional components are used to build up small circuits and to perform experiments respecting hydraulic and pneumatic laws of nature. Based ...

The viscous flow in the fluidic amplifier is simulated numerically based on CFD technology, and many tests have been done to verify the numerical precision. The results show that the calculated data are good agreement with the experimental data. So the numerical simulation of the viscous flow in the fluidic amplifier is accurate and reliable, and it can be applied to investigate the steady flow...

A compact model to compute flowrate and pressure in micro-fluidic devices is presented. The micro-fluidic flow can be driven by either an applied electric field or by a pressure gradient or both. In the proposed compact model, the complex fluidic network is simplified by using an electrical circuit. The compact model can predict the flowrate, pressure distribution and other basic characteristic...

Purpose – The functionality of personal mobile electronics continues to increase, in turn driving the demand for higher logic-to-memory bandwidth. However, the number of inputs/outputs supported by the current packaging technology is limited by the smallest achievable electrical line spacing, and the associated noise performance. Also, a growing trend in mobile systems is for the memory chips t...

A family of self-aligning micromachined fluidic couplers are presented here. Bulk micromachined and DRIE processed silicon structures have been investigated as a means of providing external connections via fused silica capillaries for MEMS fluidic devices. These couplings can have arbitrary geometry, ensuring compatibility with most fluidic ports. In addition, performance exceeds typical requir...

Fluctuations in flow rate invariably occur in microfluidic devices. This fluidic instability results in a deteriorating performance and the suspension of their unique functions occasionally. In this study, a fluidic-LPF (low pass filter), which is composed of an ACU (air compliance unit) and a FCSP (fluidic channel with high fluidic resistance for sufficient preload), has been proposed for prov...

The interest of microelectronic fluidic arrays for biomedical applications, like DNA determination, is rapidly increasing. In order to evaluate these systems in terms of required Design-for-Test structures, fault simulations in both fluidic and electronic domains are necessary. VHDL-AMS can be used successfully in this case. This paper shows a highly testable architecture of a DNA Bio-Sensing a...
