A micro-electrohydrodynamics (EHD) pump to generate an oscillating flow is newly developed and experimentally tested. The EHD pump is the overall dimensions of 30 ×30×7.8 mm and has a pumping channel of 24×24×0.9 mm which is bend in parallel. In order to generate symmetric oscillating flow, alternate voltage was applied. Experimental results indicate that the newly developed pump is the twice as good as previous pump at static pressure and flow rate. A new model pump generated up to 550 Pa at an applied voltage of 1kV. New model pump generate higher static pressure and higher flow rate by the use DBS in place of DBE at working fluid. The amplitude of oscillating flow become smaller with decreasing the frequency.
