EWOD driven droplet microfluidics platform. (A) The electrowetting effect: the change of the wetting properties of a hydrophobic surface with an application of a voltage V between the droplet and a counter-electrode [222]. (B) Cross-sectional schematic diagram of the two plane EWOD driving platform [222]. (C) Consecutive images of droplet splitting and droplet fusion by turning on and off different electrodes [117]. (D) Mixing within droplet by maneuvering it in an irreversible electrode pattern [126]. Top row shows the pivot point about which the droplet moves in a 2 × 3 mixer. Sequential images of droplet mixing at 16 Hz (2-4 row).
