Abstract

Electrowetting-On-Dielectric (EWOD) is becoming a standout amongst all the broadly used method for controlling small amount of liquid on a flat electrode surface. Scaling down the EWOD process has been a technological development recently as it appeared to have better integration and automation of numerous procedures on a single device. The applied voltage plays an important role in this study. A low voltage will diminish the ionization effect happening within the droplet. Insufficient ionization will further cause the inability of droplet movement. Therefore, a high voltage must be applied to initiate droplet movement. This study focuses on high voltage switching system for electrowetting process. Results achieved shown that MOSFET IRF 740 acted as the best switching component for the system. Besides, this study proves the feasibility of electrowetting by describing the fabrication and testing of different dielectric layers using high voltage switching system. As for the coating of dielectric layer, cooking oil showed the most noticeable results out of all the materials
