摘要： The invention relates to an optical electrowetting device comprising a conductive fluid (5; 101) and a non-conductive fluid (4; 102), said fluids being non miscible, and an insulating substrate (2; 103) on which both fluids are in contact and form a triple interface, wherein the natural contact angle (105) of the non-conductive fluid (102) on the substrate (103) in presence of the conductive fluid (101) is comprised between 0° and about 20°. This device may be a variable focus liquid lens, an optical diaphragm, an optical zoom. The invention further relates to an apparatus such as a camera, a cell phone, an endoscope or a dental video camera, comprising said electrowetting device and a driver or electronic means for controlling the lens.

摘要： 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.
