Electrohydrodynamic atomisation (EHDA) is an emerging technique for the production of micron and nano-scaled particles. The process often involves Taylor cone enablement, which results in a fine spray yielding formulated droplets, known as electrospraying, which then undergo drying during deposition.

Multi tip devices have been designed and engineered to be utilised in potential up-scaled EHDA, in comparison to the traditional single needle system.
