Determination of droplet shape in digital microfluidic systems using two-dimensional flow analysis

Ahmadi A., Najjaran H., Holzman J.F., Hoorfar M., University of British Columbia Okanagan, CA

A two-dimensional model for fluid flow in a digital microfluidic system is introduced, and the results are compared to experimental data. Resistive flow effects based upon contact line forces, filler effects and shear forces are [...]

Numerical Modeling of Microdrop Motion on Digital Microfluidic Multiplexer

Ahmadi A., Najjaran H., Holzman J., Hoorfar M., University of British Columbia, CA

This paper introduces a computationally efficient numerical modeling approach for microdroplet motion on an innovative Digital Microfluidic Multiplexer structure which enables the pilot synthesis and study of nanoparticles. This structure offers an enhanced level of [...]

Levitation of a Charged Microdroplet

Schildknecht A., Hofer E.P., University of Ulm, DE

A new method for levitation of a charged microdroplet is presented. The feedback-control consists of high-speed camera, flatness based follow-up controller and high-voltage amplifier.
