A -- COMMERCIALIZATION OF MAGNETOHYDRODYNAMIC (MHD) MICROPUMP TECHNOLOGY SOL CBD99-018 DUE 100499 POC Veronica Lanier (925) 422-6416 LAWRENCE LIVERMORE NATIONAL LABORATORY SEEKS PARTNERSHIPS WITH INDUSTRY TO COMMERCIALIZE MAGNETOHYDRODYNAMIC (MHD) MICROPUMP TECHNOLOGY Announcement: Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U.S. Department of Energy (DOE), is seeking one or more industrial partners to commercialize magnetohydrodynamic (MHD) micropump technology. LLNL has developed an AC magnetohydrodynamic (MHD) micropump and microsensor which utilizes micromachining to integrate the electrodes with microchannels. An electromagnet produces magnetic fields perpendicular to both the electrical current direction and the fluid flow direction. The MHD micropump for example can generate continuous, reversible flow, with readily controllable flow rates. Flow speeds and direction can be varied by manipulating the electric current, the magnetic field and the phase between the two. By mismatching the electrodes, a swirling vortex flow can be generated for potential mixing applications. No moving parts are necessary and the dead volume is minimal. The micropumps can be placed at any position in a fluidic circuit and a combination of micropumps can generate fluidic plugs and valves. Note: This is not a procurement. Companies interested in commercializing the MHD micropump should provide a written statement of interest that must include a description of corporate capability and experience relevant to commercialization of microfluidic devices. Statements of interest should be sent to: Lawrence Livermore National Laboratory Industrial Partnerships and Commercialization Office P.O.
