Abstract
An electrochemical sensor strip is provided. The electrochemical sensor strip includes an insulating substrate having a reaction concavity integrally formed thereon, a cover, an electrochemical reaction layer, and an electrode device. The reaction concavity is peripherally and entirely enclosed by the insulating substrate. The cover partially covers on the reaction concavity by leaving an opening on the reaction concavity. The electrochemical reaction layer is located in the reaction concavity, and the electrode device is located in the reaction concavity for transmitting a signal resulting from an electrochemical reaction performed in the electrochemical reaction layer.
