Electrochemical-sensor design
First Claim
1. An electrochemical test sensor adapted to assist in determining the concentration of an analyte in a fluid test sample, the sensor comprising:
- a base that assists in forming an opening for introducing the fluid test sample;
a working electrode being coupled to the base;
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 being located downstream relative to the opening and at least a portion of the working electrode, the sub-element being 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 test sample.

Abstract
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.
