Abstract: Embodiments generally relate to systems and methods for separating an emulsion in a cavity of a device such as a liquid lens device. In one embodiment, the method comprises at least one of: applying a bias voltage to electrodes in the device, causing at least one of droplet migration, flattening of large droplets, and reduced droplet surface tension; applying an oscillating actuation voltage waveform comprising an actuation frequency to the electrodes, such that fluid pumping and turbulence is created within the device cavity; and applying an oscillating excitation voltage waveform comprising an excitation frequency to the electrodes, such that the varying electric field created by the oscillating voltage causes small droplets of the first liquid to coalesce.

Abstract: Embodiments generally relate to methods for preventing the formation of an emulsion in a liquid lens. In one embodiment, the method comprises fabricating a top substrate, a bottom s substrate, and a central substrate including a cavity configured to be filled by first and second liquids. The liquid lens comprising the top substrate, the bottom substrate and the central substrate is assembled, with at least one of the top substrate and the bottom substrate in the assembled liquid lens being characterized by a stabilizing feature determining that in response to an impact load on the assembled liquid lens that would cause localized pressure drops of 10 maximum magnitude X in the absence of the stabilizing feature, the maximum magnitude of localized pressure drops within the liquid lens is smaller than X.
