Abstract
Experimental technique is proposed to excite oscillations of a hanging liquid droplet by applying interfacial dielectric force directly upon the droplet surface. The force proved to be applicable for all kinds of liquids and solutions including non-conductive, isolating liquids. The oscillations are detected optically, with the help of a laser beam. The measured resonant frequency modes and resonance half-widths may be used to retrieve information about the surface properties of the droplet (surface tension and surface charge, in particular). The method is applicable to a wide variety of liquids and interfaces. Possible applications are analyzed and discussed.
