| dc.description.abstract | This thesis proposes to use portable hand-operated microfluidic devices Micropumps and valves, hoping to achieve a progressive and simplified micromixer microfluidic system. Channel design and driving force are related in the micromixer system. In addition to the hand-operated type, micromixer requires the use of applied mechanical, electromagnetic and magnetic forces to control pumps and valves, and the flow channel must be limited to a fixed form design to complete, which will reduce portability and increase cost.
In order to make the portable micromixer easy to operate, simple to use, and can be produced in a short time, this thesis applies the concept of intelligent manufacturing and processing methods and the idea of simple laboratory. In the process, the simple manufacturing laboratory provides many alternatives for the clean room process, low-cost manufacturing equipment, such as CNC engraving machines, laser cutting machines, and 3D printers. Using commercially available materials for processing, sharing resources and design on the network platform, we tried to discuss and develop the materials, tools and construction methods of new microfluidic devices to stimulate personal creativity and innovation.
This research uses the concept of smart manufacturing methods to standardize the process to achieve the concept of a simple laboratory. The verification method starts with the production of the front-end molds of the process, with three different material properties: brass, PMMA (polymethyl methacrylate) and silicon wafer molds. Then it discusses several common low cost equipments in the production of middle microchannel. After that, there is a simple and fast joining method at the end, and then through three commercial and academic cooperation cases to verify and explain it. What’s more, it further extends the above-mentioned simple process concept to produce a handheld portable micromixer device, with the integration of portable microfluidic devices micropumps and valves. Finally, at the end of this thesis, the design and testing of progressive mixing effects are carried out. | en_US |
