FIG. 1.

(a) Scheme of the acoustic device geometry. The flow direction is indicated by the arrow. A first pair of interdigitated transducers emits along the crystal strong axis Z which coincides with the main flow direction. A second pair emits along the perpendicular direction (Y axis). (b) Principle of frequency modulation to move particles. (c) Image of two oil droplets trapped in the acoustic chamber 1 mm wide and high.

FIG. 2.

(a) Frequency versus time illustration of the modulation function. Left: "elliptical" motion, . Right: "house," . The trajectories corresponding to modulations sequences A and H are shown by the arrows. (b) Superimposed images of particlesmotions. IDT pairs frequency for the standing waves: . Left: Silicone oil droplets. Right: White blood cells. (c) Time evolution of the position of a silicone oil droplet position along flow (Z-axis) and transverse to the flow (Y-axis) and comparison with the model with fitting parameters and .

FIG. 3.

Total amplitudes of the periodic trajectories travelled by hRBCs and silicone oil droplets along the flow () and transverse to the flow () direction as a function of the maximum calculated drift velocity (). The values are normalized from the amplitude of the total standing wave displacement 2L. The continuous line showing plateaus corresponds to the numerical integration of Eq. (1) for oil droplets.

FIG. 4.

Sketch of the 3D motion of a particle actuated by SAW propagation. The acoustic wave inside the liquid is at the same time a standing wave in a plane parallel to the surface (YZ plane), and propagating along the perpendicular direction (X), since it is a superposition of two leaky waves, i.e., , where k is the SAW wavevector, the Rayleigh angle, and the acoustic wavevector in the liquid.
