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)
A new dual-electrode flow sensor has been fabricated by piling the microporous membrane electrodes which have 7-10μm thickness. The electrode was prepared by sputtering of platinum onto both sides of the membrane filter which contain a smooth flat surface as well as cylindrical pores with uniform diameters. The electrolysis is performed when the sample(More)
A new flow-injection/anodic stripping voltammetry has been demonstrated to assess ultra-trace mercury(II) using track-etched microporous membrane electrodes. The electrodes were prepared by the sputtering of gold or platinum onto both sides of a membrane filter with a smooth flat surface and with cylindrical pores having uniform diameter. The deposition of(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)
