Abstract

In this work, we have presented a low-cost fabrication and modeling of an electro-osmotic flow (EOF) device. The presented fabrication approach eliminates the need of expensive UV lithography and plasma setups. The polydimethylsiloxane (PDMS) microfluidic device for EOF is fabricated using simple printed circuit board (PCB) as a mold. The device is bonded with glass using adhesive bonding technology hence eliminates the need for plasma. The in-house low cost microfluidic characterization setup is used for experimental study. The obtained characteristics are modeled by the mesoscopic lattice Boltzmann method (LBM) in which the Poison Boltzmann equations is successfully coupled to capture the electrical double layer (EDL) physics. From the obtained results, it is shown that the directional transport of a bulk fluid can be achieved by EOF mechanism by suitably switching the electrodes. The experimental velocity characteristics show good agreement with the simulated results. Thus, easy coupling of LBM can be used as a tool to design and investigate such MEMS devices.
