| 20110203926 | ELECTROCHEMICAL SENSOR WITH CONTROLLED VARIATION OF WORKING ELECTRODE - An electrochemical sensor includes a dielectric substrate and a conductive layer formed on a surface of the substrate. The conductive layer includes a working electrode, an electrode lead and a connecting arm connecting the working electrode to the electrode lead. A dielectric layer is positioned over the conductive layer. The dielectric layer has an aperture exposing the working electrode and a portion of the connecting arm. The working electrode, electrode lead and connecting arm may be formed by laser ablation technique to provide precise working electrode sensor parameters. | 08-25-2011 |
