The effects of various moisture contents (ranging from 50 to 2500 ppm) in a dielectric liquid on electrohydrodynamic (EHD) pumping have been investigated. The static pressure and the flow rate induced by the EHD pump were examined using dibutyl sebacate (DBS) as the working fluid. One of the additives in DBS was deionized water. It was found that the(More)
An ion-drag pump consisting of microscale electrodes was built. The electrodes were fabricated as a series of planar comb fingers. The electrodes were paired as an emitter and a collector with a 10 mum width and 20 mum gap between them. The number of electrode pairs was 60 and the gap between the electrode pairs was 200 mum. The electrodes were fabricated(More)
An experimental investigation was conducted to develop an electrohydrodynamic (EHD) pump based on a microelectromechanical system (MEMS) technology. To develop an EHD micropump with enhanced pumping performance, including not only long-term driving but high-pressure generation, two electrode plates were prepared. On one, the electrode pattern was designed(More)
