摘要： A test strip with a sample receiving chamber having a novel flared portion that terminates in a sample receiving opening. The flared portion provides a reservoir from which sample fluid can be drawn into the capillary or sample receiving chamber. The wider opening provided by the present invention is easier to “target” with a sample fluid. In preferred embodiments, the hydrophilic reagent layer extends to the dosing end or side of the test strip and further promotes wicking of the sample into the sample receiving chamber and thus reduces dose hesitation. In other preferred embodiments, a tapered dosing end is provided on the test strip in combination with the flared portion, and this combination create a test strip that will draw sample fluid into the sample receiving chamber regardless of where along the dosing edge of the test strip the fluid sample makes contact.

摘要： An electrochemical biosensor with electrode elements that possess smooth, high-quality edges. These smooth edges define gaps between electrodes, electrode traces and contact pads. Due to the remarkable edge smoothness achieved with the present invention, the gaps can be quite small, which provides marked advantages in terms of test accuracy, speed and the number of different functionalities that can be packed into a single biosensor. Further, the present invention provides a novel biosensor production method in which entire electrode patterns for the inventive biosensors can be formed all at one, in nanoseconds—without regard to the complexity of the electrode patterns or the amount of conductive material that must be ablated to form them.

摘要： A biosensor having multiple electrical functionalities located both within and outside of the measurement zone in which a fluid sample is interrogated. Incredibly small and complex electrical patterns with high quality edges provide electrical functionalities in the biosensor and also provide the electrical wiring for the various other electrical devices provided in the inventive biosensor. In addition to a measurement zone with multiple and various electrical functionalities, biosensors of the present invention may be provided with a user interface zone, a digital device zone and/or a power generation zone. The inventive biosensors offer improved ease of use and performance, and decrease the computational burden and associated cost of the instruments that read the biosensors by adding accurate yet cost-effective functionalities to the biosensors themselves.

摘要： A biosensor is provided that includes first and second plate elements, wherein each plate elements has first and second ends and first and second lateral borders. In addition, the biosensor includes a spacer positioned to lie between the first and second plate elements so that at least a portion of the first and second plate elements cooperate with one another to form opposite walls of a capillary space. Further, the first ends and at least a portion of the lateral borders define a fluid sample-receiving portion in communication with the capillary space. Electrodes are positioned in the capillary space of the biosensor.
