Abstract:
1. An electrochemical device having a sample-receiving end and a connector end comprising, in sequence: (a) a first substrate, having a layer of conductive material applied to a first surface thereof; (b) an electrically-resistive middle layer, and (c) a second substrate, having a layer of conductive material applied to a first surface thereof; wherein the first surface of the first substrate and the first surface of the second substrate are adhered to the electrically resistive middle layer; wherein the device has a first sample space, said first sample space passing through electrically resistive middle layer and being bounded on opposing sides by a portion of the conductive material of the first substrate forming an unpatterned first electrode and a portion of the conductive material of the second substrate forming an unpatterned second electrode, and wherein the connector end comprises first and second connectors, said first connector having two separate contact pads and said second connector having at least one contact pad, wherein the first and second connectors extend from a common edge of the device and have open space therebetween, wherein the contact pad or pads of the second connector are between the contact pads of the first connector when viewed in the plane of the strip, and wherein if a conductive portion of the first connector faces a conductive portion of the second connector within the connector end of the device they are separated by the electrically resistive middle layer.
