INTERDIGITATED ARRAY AND METHOD OF MANUFACTURE
First Claim
1. An automated feed manufacturing product, comprising:
- a flexible substrate having a plurality of card zones with the card zones defining sensing areas with sensor units formed within the sensing areas, the sensor units having a first electrode having first fingers, and a second electrode having second fingers and with the first fingers interleaved with the second fingers and with the first fingers spaced away from the second fingers, the sensor units also comprising biomolecule receptors on the web between the first electrode and the second electrode such that a physical property of the first electrode relative to the second electrode is effected upon one or more of the biomolecule receptors binding to a biomolecule.

Abstract
An automated feed manufacturing product is disclosed. The automated feed manufacturing product is provided with a flexible substrate having a plurality of card zones with the card zones defining sensing areas with sensor units formed within the sensing areas. The sensor units have a first electrode having first fingers, and a second electrode having second fingers and with the first fingers interleaved with the second fingers and with the first fingers spaced away from the second fingers. The sensor units also comprising biomolecule receptors on the flexible web between the first electrode and the second electrode such that a physical property of the first electrode relative to the second electrode is effected upon one or more of the biomolecule receptors binding to a biomolecule. The automated feed manufacturing product can be formed as a continuous web, or discrete sheets formed using a sheet feeder that picks up and processes the discrete sheets.

8. A method of making a sensor card, comprising the steps of:
-
applying a first conductive ink to a substrate in a first pattern to form a first conducting element and a second conducting element, the first and second conducting elements having first and second widths; applying a second conductive ink to the substrate with an aerosol jetting apparatus in a second pattern to form first fingers interleaved with second fingers, the first and second fingers having third and fourth widths that are less than the first and second widths of the first and second conducting element, the first fingers being spaced a distance from the second fingers between 10 nanometers and 1 millimeter, wherein the first conducting element and the first fingers are electrically connected to form a first electrode of a sensor unit, and the second conducting element are electrically connected to the second fingers to form a second electrode of the sensor unit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
