Abstract
With the development of micrototal analysis systems (${\mu}TAS$), which is a result of enhancement of MEMS technology, rapid progress has been achieved in medical and biological research. The study of lab-on-a-chip (LOC) devices, which are types of ${\mu}TAS$ and which integrate the functions of mixing and analyzing tiny amounts of samples and reagents on one chip, has actively progressed. An LOC comprises microfluidic components such as micromixers and micropumps. Because the flow in a microfluidic system is generally laminar, it is very difficult to efficiently mix and feed fluid reagents. This paper presents the design and the method of fabrication of an MHD micropump for mixing fluids. By using this micropump, fluids are simultaneously mixed and pumped; this is achieved by coupling the Lorentz force and force exerted by an electric charge moving in an electric field.
