Patent ID: 7081188

Claim:
An electric-current biosensor, comprising: a support including a first support and a second support, said second support being integrally connected to said first support along a folding line, wherein the second support includes a pair of testing ports formed at two sides thereof and extending exclusively through the thickness of said second support; a pair of positive and negative co-planar electrodes formed on the first support, the positive electrode having a positive electrode film and a positive conductive film, and the negative electrode having a negative electrode film and a negative conductive film; an activity area formed on the first support, said activity area covering a portion of the pair of positive and negative electrode films; a mating activity area formed at said second support between said testing ports; an electrode film formed on the second support between said testing ports; and a pair of adhesive portions formed at said second support in non-overlapping relationship in the said mating activity area; said electrode film being positioned in close proximity to said activity area as the result of folding said support along said folding line, and being maintained above the pair of positive and negative electrode films in overlapping relationship therewith by the adhesive connection of said pair of adhesive portions with said first support.
