Abstract:
PROBLEM TO BE SOLVED: To provide a gripper capable of gripping various fine bodies without the risk of applying a high volt and heat to an object, and to provide a drive method used for the same. SOLUTION: When a piezoelectric driving part 250 is extended/contracted, contact parts 230, 240 are correspondingly moved. When the contact parts are moved, links 131, 132 push and pull arms 111, 112 and nippers 151, 152 through bending structures 210, 220, and accordingly the leading ends of the nippers 151, 152 are opened and closed to grip the fine body.

Abstract:
A method of removing a sacrificial portion of a functional micro device involves forming a functional film (23) on a silicon wafer (20), forming a protective layer (25) on the functional film (23), etching the functional film (23) to open a portion of the silicon wafer (20), and etching the silicon wafer (20) by introducing XeF2 gas sublimed from a solid state into the opened portion of the silicon wafer (20). The protective film (25) may be silicon dioxide, photoresist or metal. The functional film (23) may be a micro acceleration sensor, a micro infrared sensor, a micro optical sensor or a micro-piezoelectric cantilever. When used as a piezoelectric film, the PZT film (23) may be sandwiched between a lower electrode (22) of Ti and Pt and an upper electrode (24) of Pt.
Abstract:
PURPOSE: A driving method of a capacitive touch screen is provided to reduce recognition error about a touch location by including touch position recognition resource and a force recognition resolution. CONSTITUTION: First electrodes are selected as a vertical scanning group(S902). Second electrodes are selected as a horizontal scanning group(S903). A signal corresponding to conductive capacity value is collected in a touch cell(S904). First and second electrodes are selected. A touch position is recognized by using conductive capacity which is generated from all touch cells(S910).

PURPOSE: A touch screen and a method for verifying touch information are provided to simplify a process for forming a transparent electrode by forming a single transparent electrode structure based on a transparent electrode array. CONSTITUTION: A first transparent electrode(A) and a second transparent electrode(B) are alternately arranged on a substrate such that the transparent electrodes are parallelly arrayed. A protective layer is formed on the first transparent electrode and the second transparent electrode. The transparent electrodes are in the form of zigzags. A lower substrate is formed on the protective layer. An elastic layer(40) is interposed between the protective layer and the lower substrate. A lower transparent electrode(50) faces the transparent electrodes on the lower substrate in order to function as a ground electrode. A dam(60) is formed at the edge of the elastic layer.
Abstract:
An input apparatus for a portable terminal and a method for manufacturing the same are provided to detect not only the intensity and the direction of contact force but also the on/off signal. Terminals(101,102) are formed on a printed circuit board(100). A supporting part(110) is formed on the top of the printed circuit board. The supporting part comprises penetration holes(111,112). A structure with membrane(130) is formed with the flat type on the top of the supporting part. The structure with membrane comprises membrane regions(131,132). Strain gages(151,152) are formed on the top of the membrane regions of the structure with membrane. Strain gages are electrically connected with the terminals of the printed circuit board. Load blocks(210,220) are formed on the top of the membrane regions of the structure with membrane.
Abstract:
Provided are method for providing a user interface (UI) based on touch-pressure and an electronic device using same. The method for providing a UI of the electronic device according to the present invention involves detecting the touch pressure of the touch inputted through a touch screen of the electronic device, and controlling the electronic device based on the touch-pressure. Thus, the method of the present invention can provide a variety of UIs on the basis of the pressure of the touch applied to the touch screen by a user, thereby improving user convenience and facilitating user entertainment.
