Patent ID: 7413640

Claim:
An electric-current biosensor, comprising: a support, having a first and second supports, the second support having a testing port formed on a side thereof; a positive electrode film and a negative electrode film disposed on the first support and a second electrode film disposed on a middle portion of the second support, wherein the positive electrode film and the negative electrode film are formed with an interval slit therebetween, and the interval slit extends vertically and inwardly from a side edge of the first support; a conductive film, having positive and negative conductive films electrically connected to the positive electrode film and negative electrode film, respectively; a bioactivity layer, disposed on the positive electrode film and the negative electrode film and forming an activity area, the activity area covering at least some portions of the positive electrode film and the negative electrode film; and an adhesive layer, disposed between the first and second supports to bond the first and second supports together, the testing port is disposed on the activity area; wherein the second support is folded on the first support to expose a portion of the positive electrode film, a portion of the negative electrode film, and a front end of the interval slit having the testing port.
