Abstract
A biosensor strip having an identification function includes a first insulating substrate and a second insulating substrate, and the first substrate is deposited on the second substrate, and the first substrate has an electrode and an identifying electrode area, and the electrode and identifying electrode area are exposed from the second substrate. The identifying electrode area is made by coating an electrically conductive material. Since different conductive materials have different impedances, the conductive material can be changed according to different testing applications or different sensing instruments. When the invention is used and the strip is inserted into a sensor, the impedance produced by the conductive material of the identifying electrode area or the impedance produced between the electrode and the identifying electrode area is used to determine whether or not the impedance of the sensor falls within the predetermined range; if no, then an error message will be produced to avoid any distortion of the test; if yes, then the biological test sample will be tested. As a result, it is not necessary to change the sensor, and manufacturers only need to change the factory default settings of the impedance. Unlike the prior art strip that requires changing the position and form of the identifying electrode to fit different applications or sensors of different specifications, the invention can save manufacturing cost and provide convenient uses.
