Gentle Micropump based on Microelectromagnetic Actuator

Al-Halhouli A.T., Büttgenbach S., Kilani M.I., Waldschik A., Technische Universität Braunschweig, DE

This work presents the fabrication and development of a new multifunction micropump based on integrated electromagnetic microactuator. The novel design consists of a fluidic chip, two microfabricated polymer magnets and chip cover. These components form [...]

Diamond-Hardfaced TiC/Ti Composite for Submersible Pump Bearings in Geothermal Systems

Kear B.H., Voronov O.A., Diamond Materials Inc., US

Renewable energy sources include electrical generators driven by steam from geothermal sources. Typically, the bearings of submersible pumps used in geothermal systems are hardfaced with WC/Co and WC/CoCr composites. To enhance bearing performance, we have [...]

A Hydrophobicity Controlled Nanofluidic Pump

Dharmatilleke S., Liu H., Tay A.A.O., Institute of Materials Research and Engineering, SG

interfacial energies in the system. Many methods for modulation of surface tension to manipulate fluids in micro or nano scale have been studied and reported, including the mechanical (surface roughness effect), chemical (electrochemical effect), opto- [...]

Novel piezo motor enables positive displacement microfluidic pump

Henderson D., New Scale Technologies, US

Microfluidic pumping mechanisms, such as membrane micro pumps, create a pulsed stream with generally low pressure, low flow and limited precision. We present a novel piezoelectric motor that is used to create a positive displacement [...]

Surface Micromachined Viscous Spiral Pump

Chen C-J., Galambos P.G., Haik Y., Kilani M.I., Florida State University, US

This paper introduces a new viscous micropump produced using surface micromachining technology. The pump consists of a disk with a spiral protrusion that rotates at a close proximity over a stationary plate. Fluid contained in [...]
