Microfluidics
Derek Rinderknecht

The microfluidics research in the Multiscale Fluidics laboratory is focused on developing microfluidic devices for biomedical applications, in addition to fluid control, mixing and analysis on the microscale. Currently the flow dynamics of the first impedance driven micropump are being evaluated. The micropump is comprised of an elastic tube coupled at either end to two end members of different mechanical properties, geometries or any other factor affecting wave propagation and/or reflection, which when periodically excited in a specific configuration, the accumulation of a pressure gradient results from wave interference propelling the contents in the desired direction. The flow output has been observed to be reversible, direction being highly dependent on frequency, as well as capable of reliably delivering both high and low flow rates.
