Abstract

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.
