| 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. |
