Electrowetting on dielectric for biosample handling using ZNO as hydrophobic microchannel coverage

Abstract

In this paper, we will review the electrowetting on dielectric (EWOD) principles applied to microfluidic devices. EWOD is the mechanism that can control wettability of liquids on solid surface using electric potential. In our case, we changed the teflon surface with ZnO transparent film in order to obtain a device with an optical weak absorption in the diapason ranged from VIS to far-MIR and THz waves. The microdroplet is manipulated by a microcontroller through contacts that are THz resonators at the same time. We control the moving speed and changing the pad interspacing by simulating the applied bias in Coventor software and calculated spectral analysis in Ansys for optimizing pad-THz resonator.
