Patent number: 9939630Abstract: An electrowetting optical device having a non-aqueous conductive liquid and a non-conductive liquid, the liquids being non-miscible, and a dielectric enclosure on which both liquids are in contact and form a triple interface. The non-aqueous conductive liquid includes a non-ionic polar organic solvent, and at least 2 weight % of a first compound, where the first compound is non-aqueous and is either ionic or non-ionic. If the first compound is non-ionic, the first compound is more polar than the solvent, the polarity of the non-ionic first compound being measured by Hansen parameters, a sum of the Hansen parameter for polarity (?p) and of the Hansen parameter for hydrogen bonding (?h) being higher than the sum of the corresponding Hansen parameters of the non-ionic polar organic solvent, and the non-aqueous conductive liquid having an ionic second compound.Type: GrantFiled: May 20, 2015Date of Patent: April 10, 2018Assignee: PARROT DRONESInventors: Benjamin Burger, Stéphanie Chevalliot, Géraldine Malet
