ABSTRACT
Trapping particles in microfluidics by positive dielectrophoresis
Speaker: Mike Yeksel
Advisor: Dr Boris Khusid
Monitoring used oil contaminants requires highly
sophisticated laboratory techniques. Much work is needed to improve ability to
predict and prevent failure of sophisticated Navy diesel engine components and
to schedule maintenance in most efficient time intervals. The idea of an oil
filter for marine diesel engines based on the dielectrophoretic capturing of
positively polarized particles is presented [1-5]. Its principles of operation
are described.
Broadband dielectrospectroscopy techniques used to assist efforts to simulate contaminant particle motion inside the filter and to estimate levels of contamination are introduced. Preliminary measurement results are presented.
