Abstract
An electric-current biosensor has a support, an electrode film, a conductive film, a bioactivity layer, and an adhesive layer. The support has a first support and a second support with a concave having a testing port therein. The electrode film has a first electrode film disposed on the first support and a second electrode film disposed on the second support. The first electrode film has a positive electrode film and a negative electrode film, which are formed with an interval slit therebetween. The conductive film has a positive and negative conductive films electrically connecting with the positive and negative electrode films, respectively. The bioactivity layer is disposed on the first electrode film and forms an activity area. The activity area covers at least some portions of the positive and negative electrode films. The adhesive layer is disposed between the first and second supports for bonding together.
