Electrochemical biosensor strip
First Claim
1. An electrochemical biosensor strip, comprising:
- a base;
an electrode system laid on the base, comprising a first end, a second end, at least three electrodes and a short circuit formed between two selected electrodes of the at least three electrodes;
a spacer covered on the electrode system to expose a portion of the first end for an electrical connection adapted to a meter, having an opening to expose a predetermined portion of the electrode system for applying a test reagent; and
a cover covered on the spacer.

Abstract
An electrochemical biosensor strip has a base, an electrode system, a spacer and a cover. The electrode system is laid on the base and preferably comprises at least three electrodes. There is a short circuit formed between two selected electrodes of the at least three electrodes. The spacer is laid on the electrode system and exposes a portion of the electrode system for electrical connection with a meter and a different portion of the electrode system for application of a test reagent to those exposed surfaces of electrode system. The test reagent is a reagent that is specific for the test to be performed by the strip. The cover is covered on the spacer. The short circuit is used to switch on a meter for increasing the operative convenience and further used to recognize the suitable meter. The electrochemical biosensor strip may have a rough unit formed on the base for increasing the adhesion of the test reagent for the test to be performed by the strip.
