Superposition of successive frames illustrating drop switching by local thermocapillary actuation. The arrow indicates the laser location observed by the fluorescence of the water-dye solution. (a) Qo/Qw = 5/0.05, U = 2.6 mm/s, R = 60 µm, P = 58 mW, frame rate 50 frames/s. (b) Qo/Qw = 10/0.1, U = 6.1 mm/s, R = 54 µm. P = 111 mW, frame rate 100 frames/s. (c) Qo/Qw = 15/0.2,U = 13.0mm/s, R = 55 µm. P = 159 mW, frame rate 100 frames/s. Flow rates are expressed in µl/min. Reprinted with permission from [68]. Copyright 2008, American Institute of Physics.
