Abstract
The present invention relates to a multi-phase liquid composition comprising a conductive fluid and a non-conductive fluid, the non-conductive fluid being immiscible in the conductive fluid, the composition having a mean arithmetic cinematic viscosity of between about 1.5 cSt and about 40 cSt, within a temperature range of about −20° C. to about +70° C. The invention also pertains to an optical electrowetting device comprising said multi-phase liquid composition, as well as an optical lens driven by electrowetting, and apparatus comprising the same.
