FIG. 1.

(a) Schematic of the programmable manipulation device. The microfluidic device consists of a four-port SAW device and a PDMS microchannel (not to scale). (b) Illustration of the transportation of the MBs. The MBs are trapped at the pressure nodes and transported by introducing a relative phase to the independent IDTs.

FIG. 2.

The behavior of the MBs in the microchannel (a) prior to and (b) after activation of two orthogonal SAW. (c) The enlarged image of the MB cluster. (d), (f) Transportation of MB cluster along the Y direction with the displacement of 20.25 ± 1.80. (e), (g) Transportation of MB cluster along the X direction with the displacement of 23.42 ± 2.68. The process of the transportation of the MB cluster by adjusting the relative phase to −120° in X and Y direction, respectively. (h) The composite image showing the trajectory of the MB cluster. The input power applied to the each IDTs in the X and Y direction is 93.2 mW and 41.7 mW, respectively. The scale bar is 20 µm (enhanced online).
