| 20110008245 | METHOD FOR MANUFACTURING NANOSTRUCTURE AND NANOSTRUCTURE MANUFACTURED BY THE SAME - Provided are methods for producing nanostructures and nanostructures obtained thereby. The methods include heating a certain point of a substrate dipped into a precursor solution of the nanostructures so that the nanostructures are grown in a liquid phase environment without evaporation of the precursor solution. The methods show excellent cost-effectiveness because of the lack of a need for precursor evaporation at high temperature. In addition, unlike the vapor-liquid-solid (VLS) process performed in a vapor phase, the method includes growing nanostructures in a liquid phase environment, and thus provides excellent safety and eco-friendly characteristics as well as cost-effectiveness. Further, the method includes locally heating a substrate dipped into a precursor solution merely at a point where the nanostructures are to be grown, so that the nanostructures are grown directly at a desired point of the substrate. Therefore, it is possible to grow and produce nanostructures directly in a device. As a result, unlike the conventional process, it is not necessary to assemble and integrate the nanostructures produced in a sacrificial substrate into a device. | 01-13-2011 |
| 20110000060 | FLEXIBLE PIEZOELECTRIC DEVICE AND FLEXIBLE CAPACITOR MANUFACTURED BY THE SAME, AND MANUFACTURING METHOD FOR FLEXIBLE SENSORS - Provided are a method for manufacturing a flexible device, a flexible device, a flexible piezoelectric device and a flexible capacitor manufactured by the same, and a method for manufacturing a flexible sensor. A method for manufacturing a flexible device includes: laminating a first metal layer on a silicon oxide layer on a silicon substrate; laminating a device on the first metal layer; annealing the first metal layer to oxidize the first metal into a first metal oxide; etching the first metal oxide so as to separate the device from the silicon oxide layer; and transferring the separated device to a flexible substrate using a transfer layer. According to the disclosed method for manufacturing a flexible device, differently from the prior art where the silicon substrate itself is etched, the metal oxide layer laminated on the silicon substrate is etched to separate the device from the substrate. As a result, physical damage of the silicon substrate may be prevented and the cost of using the expensive single-crystal silicon substrate may be reduced. | 01-06-2011 |

| 20100202030 | VARIABLE VIEW IMAGING SYSTEM WITH COMBINATION OF TELECENTRIC SCANNER AND DOUBLE WEDGE PRISMS - A variable view imaging system for observation of micro object with variable view orientation and position includes a telecentric lens group, a scanning mirror, wedge prisms, a deformable mirror and related optical elements. The combination of a scanning mirror and a telecentric lens group decouples the motion of scanning mirror and the view angle. The view angle is determined only by the angle of the wedge prisms. This design increases the zenith angle of the view and simplifies the kinematics of the system. The wedge prisms and the scanning mirror can supply a flexible view in a compact way. The wavefront error induced by the wedge prisms is corrected by the deformable mirror. In order to achieve the desired view state during operation, the scanning mirror angle and the wedge prisms angle are calculated iteratively based on the kinematics and Jacobian matrix of system. | 08-12-2010 |
