Investigation of Time Based Pressure Control for Microfluidics Chip Design

Abstract

Micro-Electro-Mechanical Systems (MEMS) is an electromechanical integrated system where the feature size and operating range of the components are on a micro scale. Unlike conventional mechanical processing, MEMS device uses semiconductor manufacturing, which includes surface microprocessing and batch microprocessing, which can be compatible with an integrated circuit. These devices or systems have the ability to detect, control, activate, and create macro scale effects.

In this study, three different microfluidic chips are designed. Three-dimensional drawing environment where microfluidic design has been prepared. The design completed in any of these three-dimensional environments requires preliminary analysis and testing in a virtual physical environment. For test and trials need a program so, we helped a program for testing to obtain and preview also evaluate the designed chips in pressure and velocity. After the original design, pressure and velocity tests were carried out depending on the material and time from micro channels by using a sample fluid model, which is similar to a modeling of the combinations in the laboratory environment, but with a very small nano- or micro-liter level. At the same time, the flow directions of the fluids in the inlet and outlet channels are observed according to the change of pressure.
