Abstract: An apparatus and a method for measuring a thickness of a skin using an image sensor are provided to remove any side effects to a living body when measuring the thickness of the skin. An apparatus for measuring a characteristic of a skin(30) includes a light source(10), an image sensor(40), and a characteristic analysis device(50). The light source generates first wavelength light of 700 to 1350 nm or second wavelength light of 1500 to 1700 nm to a specific region of an object. The image sensor measures a characteristic of the first wavelength light or the second wavelength light diffused and impinged to the object from the light source outside the object. The characteristic analysis device analyzes an internal characteristic of the object through the data measured by the image sensor.

Abstract: PURPOSE: A method for packaging a micro structure is provided to use an inexpensive plastic package of a surface mounted device type instead of a dual in-line package by packaging a portion moving in devices like an acceleration sensor, an angular velocity sensor and an actuator in a wafer level. CONSTITUTION: A micro structure is composed of a structure wafer and a cover wafer(40) on the structure wafer. A silicon direct bonding wafer has a silicon layer(30) having the same thickness as the structure and a sacrificial layer(31) between the silicon layer and the wafer. The sacrificial layer is etched to make the structure move. The cover wafer having an adhesion layer(44) is bonded to an upper portion of the silicon direct bonding wafer prepared by an electrical process. The cover wafer comes to have a desired thickness by using lapping and a chemical mechanical polishing(CMP) process. A through hole(46) is formed in the bonded cover wafer by a silicon anisotropical etching process. Metal layers(48) are formed on the cover wafer having the through hole and in a pad on the structure wafer. The wafer completed by an electrical process is sawed into unit devices. Lead frames are bonded to the unit devices, and interconnected by metal wires. A molding process using plastic is performed.

Abstract: PURPOSE: A method for manufacturing a low temperature sintering piezoelectric composition is provided to improve a physical property of a piezoelectric material composed of a substituted piezoelectric composition and to decrease a sintering temperature. CONSTITUTION: Mass regarding a composition of either a substituted low temperature sintering PZT-based piezoelectric material or composite 3-component low temperature sintering PZT-based piezoelectric material, is measured. The low temperature sintering PZT-based piezoelectric compositions of which mass is measured, are mixed while calcined. Mass of BaO-CuO as a low temperature sintering agent is measured and mixed with the calcined low temperature sintering PZT-based piezoelectric composition. The low temperature piezoelectric composition is heated to a predetermined temperature and sintered. An electrode is formed on the sintered low temperature piezoelectric material, and an electric field is applied to perform a polarization process. Power is applied to the electrode to determine a physical property of the low temperature piezoelectric material.

Abstract: PURPOSE: A printer head is provided to reduce the size of the device a half when trying to obtain the same displacement since the displacement can be improved more than two times with the same material and driving voltage. CONSTITUTION: A printer head unit including an ink chamber and a nozzle is composed of a diaphragm covered with the ink chamber of the printer head unit, a piezoelectric film repeatedly arranged on the upper part of the diaphragm at a regular interval to form polarization in the same direction as a diaphragm face and an electrode repeatedly formed in a space between the both ends of the piezoelectric film. Herein, an electrode material(113) is sprayed in an empty space of a photo register by using a metal mask, and the remaining photo register is removed after spraying the electrode material. Then the electrode(113) is repeatedly formed in a series along with the piezoelectric film(107) and a silicon film(101).
