When a meniscus of a highly conducting, low viscosity liquid hanging from a capillary tube is subjected to an intense electric field, it stretches in the direction of the field and the tip of the elongated meniscus develops a liquid ligament that eventually detaches to form a droplet (figure 1.a). After the droplet emission, the meniscus recedes to its original shape. If the meniscus is fed with liquid at a proper constant flow rate, this emission process may become periodic for a range of applied voltages between the meniscus and its surroundings. This emission regime is known as electric-microdripping (M. Cloupeau and B. Prunet-Foch, Journal of Aerosol Science, 25, 1021–1036, 1994).
