Abstract: A biosensor including a capillary chamber having an inner boundary, a working electrode including an effective working electrode portion positioned within the capillary chamber, and a counter electrode including an effective counter electrode portion positioned within the capillary chamber, and with the working and counter electrodes each having a neck that constitutes the sole portion of the electrodes that extends across the inner boundary and out of the capillary chamber. In one embodiment, the effective working electrode portion defines an average working electrode width, and the working electrode neck defines a working electrode neck width that is reduced relative to the average working electrode width. In another embodiment, a ratio between the area of the effective working electrode portion exposed to the capillary chamber and the area of the effective counter electrode portion exposed to the capillary chamber is substantially constant as a position of the inner boundary of the capillary chamber is varied along a length of the working and counter electrode necks.

Abstract: Some embodiments of the invention include a 2 -up manufacturing technique for producing test strips (100) to reduce costs, reduce waste, and increase output. Other techniques relating to the 2 -up technique, such as simultaneously manufacturing test strips (100) arranged in multiple columns, are also disclosed. Yet other techniques include cutting through the upper (110) and lower substrates (130) to form an overhang of either the upper (110) or the lower substrate (130). Other embodiments include a dual -use biosensor in which a user can apply a sample of bodily fluid to both test strips simultaneously.

Abstract: A test strip for measuring a signal of interest in a biological fluid when the test strip is mated to an appropriate test meter, wherein the test strip and the test meter include structures to verify the integrity of the test strip traces, to measure the parasitic resistance of the test strip traces, and to provide compensation in the voltage applied to the test strip to account for parasitic resistive losses in the test strip traces. In addition, conductive traces are positioned to ensure structural interrogation of all electrodes and traces present upon the test strip.

Abstract: Se describe una tira sensor de prueba de analito que tiene información codificada en la misma así como un método para formarla y conducir una prueba de analito utilizando la tira sensor de prueba. La información relacionada con un atributo de la tira o grupo/lote de tiras puede codificarse con base en los valores de resistencia pertenecientes a los aspectos eléctricos de la tira, tal como un elemento resistivo primario y un elemento resistivo secundario, el elemento resistivo secundario tiene uno de una pluralidad de estados definidos por un lugar de un conector cerrado para formar una trayectoria resistiva única para el elemento resistivo secundario que incluye una porción del elemento resistivo primario dependiendo de la ubicación del conector cerrado. Los estados pueden formarse en la tira por medio de un paso de procesamiento secundario en la fabricación de la tira en donde una pluralidad de conectores se separa dejando solamente un conector en estado cerrado.

Abstract: An analyte test sensor strip is disclosed having information coded thereon as well as a method of forming the same and conducting an analyte test using the analyte test sensor strip. Information relating to an attribute of the strip or batch/lot of strips may be coded based on resistance values pertaining to electrical aspects of the strip, such as a primary resistive element and a secondary resistive element, the secondary resistive element having one of a plurality of states defined by a location of a closed tap to form a unique resistive path for the secondary resistive element that includes a portion of the primary resistive element depending on the location of the closed tap. The states may be formed on the strip by a secondary processing step in the manufacture of the strip in which a plurality of taps are severed leaving only one tap in a closed state.
