Abstract

A disposable electrochemical sensor strip is provided. The sensor strip includes an isolating sheet having at least a through hole, at least a conductive raw material mounted in the through hole, a metal film covered on the conductive raw material to form an electrode which comprises an electrode working surface for processing an electrode action, and an electrode connecting surface, at least a printed conductive film mounted on the isolating sheet and having a connecting terminal for being electrically connected to the electrode connecting surface, and a signal output terminal for outputting a measured signal produced by the electrode action.

Claims

1. A method for manufacturing a disposable electrochemical sensor strip, comprising steps of:

providing an isolating piece having at least two recesses;

preparing a conductive assembly comprising a first and a second conductive raw materials;

forming a modified electrode through modifying said first conductive raw material; and

forming said disposable electrochemical sensor strip through positioning said modified electrode and said second conductive raw material in said at least two recesses.

2. The method according to claim 1 further comprising an electroplating procedure for modifying said first conductive raw material to form a metal film and obtain said modified electrode.

3. The method according to claim 1 further comprising a printing procedure for forming at least a signal output terminal through printing at least a conductive film on said isolating piece to be electrically connected to an output signal of said electrode.

4. The method according to claim 1 further comprising a chemical reagent immobilizing procedure for modifying said electrode to obtain an enzyme electrode.
