Biosensor with multiple electrical functionalities
First Claim
1. A biosensor for analyzing a fluid sample, comprising:
- a test strip;
the test strip defining a measurement zone having a sample receiving chamber in which is disposed a measurement electrode for detecting the presence or concentration of an analyte in the fluid sample, the sample receiving chamber including a reagent which reacts with the fluid sample, the test strip including a dosing edge wherein the sample receiving chamber is open at the dosing edge to receive the fluid sample;
the test strip further defining a user interface zone in which is disposed an electrically driven signal generator which emits a visible, audible or tactile signal upon occurrence of a triggering event, further wherein the signal generator comprises a light disposed proximate the sample receiving chamber, the light illuminating the sample receiving chamber upon the occurrence of the triggering event; and
the test strip including a meter insertion end having contacts thereon that are adapted to electrically connect to a test meter.

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.
