From: Sessile multidroplets and salt droplets under high tangential electric fields
Side-view thermographic pictures of three aligned water droplets (the intermediate droplet was located at the middle between two extreme droplets) (droplet volume: 2 μL, the separation between two extreme droplets: 7 mm) on the SR surface under a high voltage (the left electrode was energized and the right one grounded).
(a–g): positive voltages; (h–n): negative voltages.
