Multilayer MicrofluidicsIntroductionProblem DefinitionTo use micro processing techniques to address the problems associated with multi-level channel routing in bio-micro fluidic applications. Integrating materials application to build the layers of the multilevel micro fluidics system. Using a control system to arrange fluidic flow through the multilevel micro fluidics.Problem ScopeThe mission of this project is to create a multi-level micro fluidics system for bio-micro fluidic application. The packaging of this device should be efficient, feasible and versatile because we would want the fluid flow to reach multi-levels instead of remaining on a single layer. Active control devices will control the fluid flow. To flow from one layer to another layer we would have vertical vias or interconnects from the first layer to the next. Therefore to process this we would need the basic knowledge of materials that are feasible and current research accomplished on micro fluidics. These are mentioned in the Materials Information and Literature Research section.Due to time budget our group decided to neglect the biochemistry interactions of the fluid and the interior walls of the channels. We will only consider the fluid flow and how to transport the fluid from one reservoir to another within the system. We will be looking at many control systems that will manage the fluid flow throughout the channels and interconnects. All the control systems we will be discussing will be internally integrated within the micro fluidics system. The design of the control system will be discussed more thoroughly in stage 3 of the Devices Design Stages. Therefore the biochemistry interactions will not be discussed in our report due to time constraints, and we will not use external control systems.Initial Materials Informationi.

This is can be shown visually in Figure 1.The initial micro-channel design consists of only 2 layers with interconnects. The initial design purpose is only used to test if the fluid flows through channels. Controls are neglected in this design because if fluid cannot flow through the channels then adding controls are not necessary.Brief summary of each Device Design Stage up to the final design Selectionvi.
