Abstract: The present invention disclosed a biosensor apparatus comprising a substrate on which a reaction region is defined, a fluid channel defining a path to the reaction region, and a venting means communicably coupled with the fluid channel and opening exterior of the biosensor apparatus at a perimeter side of the biosensor apparatus. The present invention allows air to exit the fluid channel through perimeter sides of the biosensor apparatus without adding significant manufacturing complexity.

Abstract: This invention relates to a non-destructive means to determine electrochemical characteristics in biosensor test strips, including first applying a cyclic oxidative and reductive electric potential onto the inspection pads connecting to the reference electrode and working electrode, on which lies a drop of enzyme reagent solution, to homogenize the electrochemical characteristics of the biosensor test strips, and then applying an inspection electric potential within a short period of time over the inspection pads connecting to the reference electrode and working electrode to measure its electrical resistance to identify any abnormal biosensor test strips if present. Afterwards, embodiments of the present invention applies a reverse electric potential, having the same time interval as the inspection electric potential, onto the inspection pads connecting to the reference electrode and working electrode to prevent degradation on mediators such as potassium ferricyanide.

Abstract: This invention discloses a biosensor test strip that comprises a substrate, on which lies a conductive layer that contains a plurality of contact pads, check pads and reaction zones, which contains a plurality of working and reference electrodes, and on which the reaction reagent is deposited. The first contact pad is connected to the working electrode, while the second contact pad is connected to the reference electrode. Furthermore, this invention discloses a biosensor test strip for multiple tests on a single strip. The biosensor test strip includes a substrate with a plurality of incisions to divide the substrate into a plurality of individual test sections.
