Abstract

A method for the function control of an electrohydrodynamic atomizer, wherein an electrohydrodynamically atomized fluid, originating from the atomizer, is applied to a body, e.g. a person, in order to coat this body at least in certain areas, wherein the atomizer-comprises a fluid tank for storing the fluid and at least one high voltage source for making available a high voltage and at least one pump unit for transporting the fluid, wherein the fluid is delivered to a nozzle arrangement of the atomizer by means of the pump unit, and wherein the fluid is atomized electrohydrodynamically at the nozzle arrangement by means of the effect of the high voltage from the high voltage source, wherein a voltage and/or a current at the high voltage source is evaluated in order to acquire a working point of the high voltage source via a current/voltage characteristic curve.
