Biosensors
First Claim
1. An analyte sensor, comprising:
- a substrate;
an electrode disposed on the substrate;
a cover;
a spacer layer positioned between the substrate and the cover and forming a sample chamber there between, wherein at least a portion of the electrode is present in the sample chamber, the sample chamber comprising a proximal end where a sample is introduced into the sample chamber and a distal end toward which the sample flows; and
an incompressible element placed between the cover and the spacer layer, said incompressible element positioned only at the distal end of the sample chamber or only near the distal end of the sample chamber and providing at least one vent in the sample chamber.

Abstract
A biosensor strip having a low profile for reducing the volume of liquid sample needed to perform an assay. In one embodiment, the biosensor strip includes an electrode support; an electrode arrangement on the electrode support; a cover; a sample chamber; and an incompressible element placed between the cover and the electrode support, the incompressible element providing an opening in at least one side or in the distal end of the sample chamber to provide at least one vent in the sample chamber. In another embodiment, the biosensor strip has an electrode support; an electrode arrangement on the electrode support; a cover; and a sample chamber, the cover having a plurality of openings formed therein, at least one of the openings in register with the sample chamber. The invention further includes methods for preparing such a biosensor strips in a continuous manner.
