  • IMPEDANCE BIOSENSOR FOR ELECTRICAL IMPEDANCE BIOLOGICAL SENSING AND MANUFACTURING METHOD THEREOF
    Publication number: 20140147336
    Abstract: An impedance biosensor for sensing concentration of a target analyte in a solution includes an insulator substrate, electrically coupled conductive trace units on the substrate, biological sensing films, and an insulator cover. Each trace unit has a first trace and a second trace, each having a sensing end portion and a connecting end portion. The biological sensing films are disposed on the sensing end portions, and have a capture layer for capturing the target analyte. The insulator cover covers the trace units and is formed with window openings that expose the sensing end portions and that cooperate with the insulator substrate to define a space for receiving the solution therein.
