Patent ID: 8211280

Claim:
A biosensor comprising: a first substrate and a second substrate; a spacer layer positioned in between the first substrate and the second substrate; a sample chamber positioned between the first substrate and the second substrate, the sample chamber having only two openings; an incompressible element positioned within a portion of the sample chamber, wherein the incompressible is a monofilament, a thread or a yarn; wherein the biosensor comprises a proximal end and a distal end, a first side extending between the proximal end and the distal end of the biosensor, and a second side extending between the proximal end and the distal end of the biosensor, and wherein the incompressible element extends from an edge of the first side to an edge of the second side of the biosensor and provides the two openings in the sample chamber, wherein the first substrate is deformable and deforms due to the incompressible element.
