FIG. 1.

(Color online) Drop formation by a pulsed EHD jet on a surface with a contact angle of . An external voltage pulse leads to cone-jet transition of the electrified liquid meniscus and produces a drop on the counter electrode (inset). The drop formation process is highly reproducible as indicated by an array of fluorescent spots as drop residue after solvent evaporation. Electrical configuration: , nozzle-to-collector , and pulse .

FIG. 2.

(Color online) Improved positioning accuracy by tuning the surface wettability. The substrates used to collect spheres are (a) chromium-coated silicon substrate ; (b) Gold-coated substrate treated with 1-hexadecanethiol, a hydrophobic reagent . Fluorescent dye is added to (b) to show the contact area between the colloidal drops and the substrate. Electrical configuration is the same as Fig. 1.

(Color online) Poisson statistics of EHD drop and place. Equally sized drops are produced by a pulsed jet from a homogeneous aqueous suspension of particles and fluorescent dye (inset). (∎): the statistics for the number of particles per drop for 200 drops; (▴): Poisson distribution for a measured average of 0.80 particles per drop. Electrical configuration: , , and pulse .
