Abstract

An easily manufactured electrochemical test strip is made with facing electrode but side by side connectors for insertion into an electrochemical test meter. Current is conducted from the electrode on one layer to a connector on the other by a conductive layer disposed adjacent the end of a spacer layer, or by displacing the layer to bring a conductive surface on it into contact with the connector.

Claims

received by the International Bureau on 02 February 2009 (02.02.2009)CLAIMS
1. A test strip comprising:
(a) a base substrate having disposed thereon a first electrode and connector track, said first electrode and connector track comprising a first electrode connector, and a second electrode connector,
(b) a dielectric layer comprising two strips of dielectric material extending longitudinally along the base substrate, said dielectric strips having an open space between them defined by inner longitudinal edges, said open space exposing a portion of the first electrode and connector track and extending less than the entire length of the base substrate, such that a first of said strips of dielectric leaves a portion the first electrode connector exposed, and the second of said strips leaves at least a portion of the second electrode connector exposed, said exposed portion of the second electrode connector being greater in length than the exposed portion of the first electrode connector,
(c) a spacer layer comprising two strips of insulating material disposed over the dielectric layer, said insulating strips having an open space between them exposing the inner longitudinal edges of the dielectric strips and extending less than the entire length of the base substrate such that a first of said insulating strips leaves a portion the first electrode connector exposed, and the second of said insulating strips leaves at least a portion of the second electrode connector exposed, said exposed portion of the second electrode connector being greater in length than the exposed portion of the first electrode connector,
(d) a conductive material disposed to make conductive contact with the exposed portion of the second electrode connector, and
(e) a top layer comprising a substrate having disposed thereon a second electrode and connector track, wherein a portion of the second electrode and connector track is disposed in opposition to the exposed portion of the first electrode and connector track, and a
