1302 Development of an Active Micro Mixer using a Magnetic Actuator

Abstract

The aim of this research is to develop an active micro mixer which is one of a micro reactor. The active micro reactor can create a turbulent flow with an actuator. Here we design and fabricate a prototype of an active micro mixer using a magnetic actuator. A ferromagnetic metal plate which is 0.1 mm in thickness arranges in a mixing chamber. This plate vibrates by magnetic fields periodically. The experimental results on vibration characteristics at 30Vp-p demonstrate 146 Hz with air and 36 Hz with water. In the estimation of micro mixer, we confirmed the effectiveness of the mixing in 0.163 s. The results indicated the availability of these devices. We represent basic characteristics of the developed active micro mixer.
