Patent ID: 8187446

Claim:
A method for manufacturing a disposable electrochemical sensor strip, comprising steps of: providing an isolating piece having a length from a first end to a second end, a first side, a second side, a recess and at least one through hole, wherein the at least one through hole is on the first end of the isolating piece and has a first opening having a size on the first side and a second opening on the second side, and the recess extends from the second opening along the length on the second side to the second end; preparing a conductive assembly comprising a conductive raw material; coating a metal film on said conductive raw material for forming a modified electrode having an electrode working surface for processing an electrode action, an output terminal and a modified electrode body between the working surface and the output terminal; and mounting the working surface of said modified electrode in said through hole to place the working surface in the first opening such that an electrode working area of the working surface is equal to the size of the first opening, the output terminal toward the second end on the second side, and the body in the recess, wherein a current measured by the disposable electrochemical sensor strip is proportional to said electrode working area.
