Patent number: 11091790Abstract: A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the ?0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay.Type: GrantFiled: December 14, 2018Date of Patent: August 17, 2021Assignee: ASCENSIA DIABETES CARE HOLDINGS AGInventors: Huan-Ping Wu, Steven C. Charlton, Amy H. Chu, Andrew J. Edelbrock, Sung-Kwon Jung, Dijia Huang

Patent number: RE45384Abstract: An electrochemical test sensor adapted to assist in determining the concentration of analyte in a fluid sample is disclosed. The sensor comprises a base that assists in forming an opening for introducing the fluid sample, a working electrode being coupled to the base, and a counter electrode being coupled to the base, the counter electrode and the working electrode being adapted to be in electrical communication with a detector of electrical current, and a sub-element being coupled to the base. A major portion of the counter electrode is located downstream relative to the opening and at least a portion of the working electrode. The sub-element is located upstream relative to the working electrode such that when electrical communication occurs between only the sub-element and the working electrode there is insufficient flow of electrical current through the detector to determine the concentration of the analyte in the fluid sample.Type: GrantFiled: September 9, 2013Date of Patent: February 24, 2015Assignee: Bayer HealthCare LLCInventors: Matthew K.
