Abstract:
The present invention relates to an electrode comprising a current collector layer between silicon active material and carbon active material having a 3D structure, and a method for manufacturing a flexible lithium secondary battery having the same, more specifically, to a flexible electrode having a 3D multi-active material and a method for manufacturing a flexible lithium secondary battery having the same, comprising the steps of: coating carbon active material paste on a plastic film; patterning the carbon active material with a mold for pattern formation; creating a current collector layer by depositing copper in an RF-magnetron sputtering method on the carbon active material; and manufacturing a second active material by sputtering silicon on the current collector layer. [Reference numerals] (AA) Carbon active material;(BB) Patterned carbon active material;(CC) Patterned carbon active material and copper deposition;(DD) Patterned carbon active material, copper deposition and silicon deposition
Abstract:
A bio sensor is provided to improve sensitivity of bio materials by adsorbing them with all four surfaces of a sensing part, and simultaneously detect various kinds of bio materials through flow of fluid containing various bio materials. A bio sensor(100) comprises a supporting part(110) having a fluid pathway(115A), and a sensing part(113) crossing over the fluid pathway and having reactant capable of reacting with bio materials injected through the fluid pathway on the surface, wherein the supporting part contains a substrate(111), an etching barrier layer(114) in the rear side of the substrate, and an insulating layer(112) in the upper side of the substrate; the sensing part has a dumbbell shape with a center part(113A) having smaller width and left and right parts(113B) having larger width which transfer the detected signal from the center part to electrodes(116) formed in both left and right part.
