abstract

The current research work in this paper involves optimizing an orthogonal electrode multifunctional system to transport biofluid. Orthogonal electrode patterned microfluidic device is known to produce high microflow velocity when excited by AC signals. This paper specifically investigates the fluid flow criterion by determining the direction and velocity in the selected electrode pattern actuated with AC signals. During the initial process, experiments were conducted at 100μm spacing between the orthogonal electrodes. The exact setup was placed on a hydrophobic surface to observe the change in the velocity. This process was then repeated with 150μm spacing. Fluid with conductivity 2.36 mS/cm was tested at voltage levels ranging between 5V to 10V at 50 KHz to 1MHZ frequency levels with an increment of 100 KHz. The goal of this research work is to increase microflow velocities by varying the electrode separation distance, flow surface, voltage and frequency. Trivial investigation also done on the possibility of micromixing using this pattern.
