Abstract: In this paper, the study and analysis to improve the Standing Surface Acoustic Wave (SSAW) microfluidic devices for particle separation are described. This study provides a theoretical analysis towards highly accurate particles separation compared to other published papers. To decrease the power consumption, the calculation of minimum AC signal power required to produce SSAW force for the separation process is briefly described and analysed. The horizontal component ratio of SSAW force and its attenuation in the liquid medium are analysed and represented. To estimate the effective width of collecting microchannels, the relations between the difference in volumes or densities of particles and the difference in the displacement of particles from the centre of the microchannel of SSAW microfluidic at the end of the SSAW force working area are represented. The separation of three different volumes of polystyrene particles and three different densities of particles in distilled water are simulated.
