Micropump with magnetic micromachine

Micropumps are studied for applications to μTAS (micro total analysis system) systems for automatic medication, and so on. The principals of the micropumps are using piezoelectric materials, SMA (shape memory alloy), etc. In this study, we propose a micropump using a magnetic micromachine. As the magnetic micromachines work wirelessly, we can obtain a wireless micropump that is suitable for the miniaturization. In previous studies, we examined the basic properties of the pump, and we found that the produced pressure could be controlled by the frequency of the applied rotational magnetic field. In this study, we examined the properties of the pump such as the pressure and the flow rate. In addition, we proposed a disposable pump system using the magnetic micromachine.
