Abstract
An implantable micro-biosensor a substrate, a first electrode, a second electrode, a third electrode, and a chemical reagent layer. The first electrode is disposed on the substrate and used as a counter electrode. The second electrode is disposed on the substrate and spaced apart from the first electrode. The third electrode is disposed on the substrate and used as a working electrode. The chemical reagent layer at least covers a sensing section of the third electrode so as to permit the third electrode to selectively cooperate with the first electrode or the first and second electrodes to measure a physiological signal in response to the physiological parameter of the analyte.
