A compact syringe-assisted vacuum-driven micropumping with a constant flow rate

Wang A., Koh D., Schneider P., Oh K.W., University at Buffalo, US

Abstract In this paper, a simple syringe-assisted pumping method was introduced. Compared with previous study [1], the proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and [...]

Fixed-Valve Micropump Simulation and Optimization

Forster F.K., Walter T., University of Washington, US

Membrane pumps with fixed-geometry valves are ex- tremely simple to fabricate and have the potential to be highly reliable and cheap due to their simplicity. We have recently implemented a means of optimizing design parameters [...]

Simulation Toolkit for Micro-Fluidic Pumps using Lumped Models

Litterst C., Streule W., Zengerle R., Koltay P., IMTEK, University of Freiburg, DE

Simulation of micro pumps is complicated by the interaction of various physical domains. The fluid structure interaction (FSI) essentially determines the dynamics of micro pumps and therefore has to be taken into account. Mesh based [...]

Characterization of Micropumps for Biomedical Applications

Haik Y., Hendrix J., Kilani M., Galambus P., Chen C-J., Florida State University, US

A novel class of micro pump was developed at the Biomagnetic Engineering Lab at Florida State University. The pump operates by utilizing the viscous effects that are dominant the micro scale and by spinning a [...]

Application of the Gaseous Cross Phenomena to Microfluidics

Sharipov F., Universidade Federal do Parana, BR

Since the size of micro fluidics is very small the gas owing through micropumps, microvalves etc. can not be considered as a continuous medium but its rarefacation must be taken into account. The rarefied gas [...]
