BIOMEDICAL ELECTROCHEMICAL SENSOR ARRAY AND METHOD OF FABRICATION

摘要

Methods for fabricating a plurality of sensors on a flexible substrate, with each sensor having associated electrodes and at least one well include (a) providing a flexible substrate material layer having a surface area defined by a length and width thereof; (b) forming a plurality of sensor elements onto the flexible substrate material layer, each sensor element comprising at lea st one metallic electrode; (c) disposing at least one coverlay sheet layer over the flexible substrate sandwiching the sensor elements therebetween; (d) laminating the at least one coverlay sheet layer having an associated thickness to the flexible substrate; and (e) removing predetermined regions of the laminated coverlay sheet layer from the flexible substrate layer to expo se a portion of the underlying metallic pattern of each sensor element and to define a well with a depth corresponding to the thickness of the coverlay sheet layer. The disclosure also describes multi-layer laminated flexible sensors and arrays of sensors with wells having enhanced well capacity and/o r depth.
