    摘要： A nozzle plate unit (100) that is designed to control an ejecting direction of ink droplets by using an electro-wetting phenomenon, an inkjet print head with the same, and a method of manufacturing the nozzle plate unit are provided. The nozzle plate unit includes at least one penetration nozzle (150), an electrode (120) divided into at least two segments (120a,120b,120c,120d) formed along an inner circumference defining the nozzle, and a hydrophobic insulating layer (140) divided into at least two segments (140a,140b,140c,140d) formed on surfaces of the segments of the electrode. When a voltage is applied between respective segments of the electrode and the fluid, a contacting angle of the fluid with the respective segments of the hydrophobic insulating layer is varied by an electro-wetting phenomenon, thereby deflecting an ejecting direction of the fluid ejected through the nozzle. The inkjet print head includes a passage plate (210,220) including an ink passage having a plurality of ink chambers (204) in which ink to be ejected is filled, an actuator (300) providing ejecting force of the ink filled in the plurality of ink chambers, and the nozzle plate unit attached to the passage plate. Accordingly, the ejecting direction of ink droplets ejected through the nozzle can be controlled in various directions and thus the image can be printed at higher DPI even when a print head with a low CPI is used.

    摘要： A liquid droplet transporting apparatus includes a first electrode (22) which is arranged on a surface of a substrate (10a), a second electrode (23) which is arranged apart from the first electrode on the surface of the substrate, an insulating layer (24) which is arranged to cover each of the first electrode and the second electrode, and a liquid repellent property on a surface of the insulating layer changes according to an electric potential difference between the electrode and an electroconductive liquid droplet on the surface, and a third electrode (124) which cooperates with the second electrode to detect the liquid droplet on the second electrode. Consequently, it is possible to transport a liquid droplet between two areas, and also to detect as to in which area out of the two areas, the liquid droplet exists.
