Sensor component and process for producing sensor component using electropol ymerization

A sensor component for detecting an analyte comprising:

• a first electrode and a second electrode;
• an insulating substrate disposed between the first electrode and the second electrode;
• a plurality of conducting polymer molecules, the conducting polymer molecules being capable of displaying a change in an electrical property in response to interaction with an analyte;
• a plurality of conductive nodes disposed on a surface of the insulating substrate;
• wherein at least some of the plurality of conducting polymer molecules are bonded to one or more of the conductive nodes such that electrical junctions are formed by conducting polymer molecules between one or more of the conductive nodes and at least one of the first and second electrode, thereby forming percolation network that electrically connects the first electrode to the second electrode;
• and
• wherein at least 90% of the plurality of conducting polymer molecules are electrically connected to the first electrode and/or the second electrode.
