Abstract: An improved disposable electrochemical test sensor designed to facilitate reducing volume of fluid samples. It has a short fluid chamber having two electrodes that functions as three electrodes (one working electrode, one reference electrode and one blank electrode). The chamber provides a reservoir from which a sample fluid can be quickly drawn into the chamber through capillary action. The novel potential reverse and curve-fitting technology of the test sensor provided by the present invention can effectively eliminate most common interferents existing in the fluid samples.

Abstract: A disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance, but no additional air escape vent. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The sampling entrance provided can draw fluid into the chamber through any part of the opening, allowing easy targeting the samples with small volume, picking up smeared samples, and added tolerance to users who jam the tip of the sensor into users' finger. The sampling entrance also serves as air escape vent. Such one opening sensor alleviates over-flow issue often encountered in convenient sensors.

The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The extra wide sampling entrance provided by the present invention can draw blood into the chamber through any part of the opening, thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.

Abstract: The present invention relates to the technical field of electrochemical detection, in particularly to a method for distinguishing between quality control liquid and real sample in an electrochemical test system with recognition device controller and recognition system. The method includes: (1) applying an AC voltage signal to the electrode surface(s) of an electrochemical test strip, (2) measuring the AC impedance angle (phase angle) value between working electrode and reference electrode after drawing a test sample into the fluid chamber of an electrochemical test strip, (3) automatically judging the test sample as quality control liquid or real sample according to the AC impedance angle value.

Abstract: An improved disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The novel extra wide sampling entrance of the test sensor provided by the present invention can draw blood into the chamber not only from the front of the sampling entrance as usual in convenient sensors, but also from the top, bottom, left corner and right corner of the sampling entrance. Thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.

Abstract: The disclosure includes a control method for test strip electrodes. The method can include inserting a test strip into a glucose meter and applying a predetermined voltage to the working electrode W of the test strip. The Method can also include applying a sample to the test strip and acquiring real-time data of current generation at the electrodes R1 and R2 of the test strip. Some embodiments can also include determining whether the electrode R1 generates current earlier than the electrode R2 or not.
