Sequential images showing particle trajectory at time 0ms, 1.3 ms and 3.3 ms. The downward bending PZT actuation creates fluid displacement, which in turn drags the particle to the left and eventually down the collection channel. The experiment is carried out under 250 Hz (e.g. sinusoidal) and 9 Vp-p PZT actuation. Sorted bead is marked by a circle.
