Abstract: The method of manufacturing a copper foil with a high elongation rate includes: preparing a plating solution by mixing a copper ion, an additive for improving conductivity, a plating inhibitor, and a plating accelerator; and manufacturing the copper foil by immersing a substrate in the plating solution and applying an electric current to the plating solution to electroplate the copper foil on a surface of the substrate.

Abstract: An ultra-micro electrode that performs electrochemical analysis and a method of manufacturing the same is provided. The method includes preparing an insulating member having a capillary shape with a hollow region, preparing a conductive wire including a conductive material with an oxidation resistance greater than an oxidation resistance of copper, inserting the conductive wire into the hollow region of the insulating member, manufacturing half-finished products by applying heat and an external force to the insulating member having the conductive wire inserted therein to stretch the insulating member and the conductive wire so that a central portion of the insulating member is thin and the insulating member and the conductive wire are ruptured at central portions thereof, forming a groove by etching the conductive wire located on a ruptured surface of each half-finished product, and forming a filling layer by filling the groove with a conductive material by a plating process.

Abstract: Provided is a heater for a cigarette-type electronic cigarette device.
