Abstract

We propose a piezoelectric micromixer that generates the unidirectional rotation of a liquid inside the hole of a metallic cube, the side length of which is a few millimeters. The simple cubic structure of the micromixer is easy to be fabricated and the miniature size is suited for portable medical devices. In this report, we built the prototype of the micromixer comprised of a metallic cube (a side length of 5 mm) with a hole (diameter of 3 mm). The prototype generated water movement of 5 rps inside the hole by applying AC voltages of 60 Vp-pand 275 kHz in experiment.
