1. A biosensor strip for detecting an analyte in a sample fluid, comprising:
a strip body including a substrate, a cover plate assembled on the substrate, a conductive portion having a surface layer and being integrally formed on at least one of the substrate and the cover plate, and a reaction channel defined by the substrate and the cover plate, wherein a partial wall forming the reaction channel is one of a partial portion and an entire portion of the surface layer of the conductive portion corresponding to the reaction channel, the conductive portion has an electric response surface, and a first signal output surface different from the electric response surface, and the reaction channel has an opening receiving the sample fluid, and an electrode hole; a working electrode embedded in the electrode hole, having an electrode acting surface corresponding to the reaction channel, and a second signal output surface different from the electrode acting surface; and a chemical reagent layer covering at least the working electrode in the reaction channel, and generating an electrochemical reaction with the analyte, wherein after the sample fluid covers the reaction channel and the working electrode via the opening, the conductive portion and the working electrode configured on the partial wall generate sensing currents respectively and output signals via the first and second signal output surfaces to determine an analyte concentration in the sample fluid. |
