| description | This project is about studies of ion-drag EHD micropump and to design a readyto-fabricate
improved design. The study mainly focuses on the factors that can
improve the pumping performance of the micropump. This report started with the
studies of theoretical aspect of microfluidics which are related to micropump system
and then the principle of the ion-drag EHD pumping. The fabrication methods of
micropump are elaborated which to find the cost effective and technically validated
fabrication. Parylene and SU-8 will be the main choice of the material due to its
cheap and easy to fabricate advantages, to form the skeletal structure of the
micropump. Gold is used as electrode of its good conductivity, low residual stress
and ease of deposition. A synthesis of comparison results of pumping performance of
ion-drag micropump from a few previous testing by other researchers is conducted.
The comparisons showed that electrode designs, electrode pair gap and channel
height played the main important roles of improving the pumping performance, and
they are all related with backflow effect of electric-fluidic field. The final design of
the ion-drag micropump is a parallel electrodes micropump, with proposed
improvement by valving structure to reduce backflow effect. |
