We report on a method for drop-on-demand printing of personalized medicines. A fluid is infused into an electrically insulating nozzle to form a pendant drop that will serve as a floating electrode that is capacitively coupled to external electrodes during a voltage pulse. An electric force is directly applied to the pendant drop to produce a sessile drop on an insulating polymer film. Versatility is proved on fluids spanning over three orders of magnitude in viscosity and conductivity. Scaling analysis captures the essential physics of drop dynamics and provides critical design guideline.
