Abstract/Summary In this paper a new method for surface acoustic wave (SAW) driven microchannel flow is introduced. This method employs a laser ablation system to create a groove type microchannel on the 1280 rotated Y-cut X-propagating Lithium Niobate (LiNbO3, LN), to provide two walls as the driving source that radiate acoustic energy into the fluid. This new configuration allows the fluid to flow in the microchannel without generate vortices for a channel width less than 50 m at a driving frequency of 30 MHz. Numerical analysis was performed and the results agreed with the experimental findings. The potential application of this new configuration for SAW driven microchannel flow is to propel fluid in Lab-on-a-chip devices.
