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.
