N2 - We present a microfluidic device for moving a fluid in a ring-shaped channel that utilizes boundary layer driven acoustic
streaming as its driving mechanism. One wall of the channel is made of a flexible material and acts as the acoustic source. To
help in the design process, a numerical study based on perturbation theory was conducted. A flexible printed circuit board is used
as an actuator, which is excited magnetically using Lorentz forces to introduce a flexural travelling wave. The resulting streaming
velocity is measured using particle tracking velocimetry and its dependence on the deflection amplitude is identified to verify the
numerical results.
