Abstract
Aspects are directed to a reference electrode integrated on a surface of a substrate to facilitate functionalization of a working electrode. The reference electrode is used in the electrochemical deposition or electrodeposition of one or more functional layers on a working electrode. The working electrode may be a sensing element of an analyte-selective sensor. Additional aspects of the current subject matter are directed to a counter electrode integrated on a surface of a substrate.

A device, comprising:
- a substrate;
- a reference electrode comprising
- a transducer positioned on an anterior surface of the substrate;
- and
- an overlay comprising a redox couple applied to a first surface of the transducer;
- and
- a working electrode positioned on the anterior surface of the substrate;
- wherein the reference electrode and the working electrode form an electrolytic cell in a fluid medium;
- wherein application of an electrical stimulus to the working electrode in the electrolytic cell provides electrodeposition of a surface layer on the working electrode.
