Abstract
In this talk, I will discuss our studies of the effects of electrical charging on liquid marbles, which are liquid droplets coated by a layer of particles and dispersed in air. These liquid marbles rely on a delicate balance of the interfacial adsorption of the particle layers and have shown numerous interesting interfacial and fluid dynamical phenomena. However, their potential has been limited by the lack of exquisite control of their properties and dynamics in a versatile manner. To impart the control demanded, we investigate the behaviors of the liquid marbles and the particle layers in response to electrical stimulation and elucidate some of the electrically induced interfacial dynamics. Building on the understanding, we construct electrical platforms for actuating and manipulating liquid marbles. We will discuss our progress and suggest potential applications that can benefit from the resulting platform.
