Abstract
The present invention provides a micro biosensor for reducing a measurement interference when measuring a target analyte in the biofluid, including: a substrate; a first working electrode configured on the surface, and including a first sensing section; a second working electrode configured on the surface, and including a second sensing section which is configured adjacent to at least one side of the first sensing section; and a chemical reagent covered on at least a portion of the first sensing section for reacting with the target analyte to produce a resultant. When the first working electrode is driven by a first working voltage, the first sensing section measures a physiological signal with respect to the target analyte. When the second working electrode is driven by a second working voltage, the second conductive material can directly consume the interferant so as to continuously reduce the measurement inference of the physiological signal.
