Abstract: A biosensor comprising an insulative substrate (1) and an electrode system arranged on the insulative substrate (1). The electrode system comprises thereon a reagent capable of reacting with a test sample. The electrode system comprises functional electrodes (2, 3, and 4) used for testing and assisted diffusion electrodes (12) used for controlling the diffusion of the reagent. The functional electrodes (2, 3, and 4) are arranged between the assisted diffusion electrodes (12). Because the assisted diffusion electrode (12) are capable of overcoming the effect of surface tension of the insulative base board, the reagent is allowed to diffuse smoothly and uniformly on the electrode system and to arrive at a predetermined position.

Abstract: The present invention provides an automatic encoding device including a first electrode, a second electrode, and a third electrode. The first electrode and the second electrode are connected through a connecting point, so that an electric parameter between the first electrode and the second electrode changes according to a parameter needing to be corrected. The present invention further provides a method for applying the automatic encoding device to various biosensors and a method for manufacturing the automatic encoding device. Positions and the number of contacts for connecting the automatic encoding device and a detection system are fixed. Therefore, connection sites on the detection system are effectively utilized. On the other hand, the automatic encoding device in the present invention can provide different parameter information by only changing the positions of the connecting points on the electrodes, the process is simple and stable, and the probability of human errors is reduced.

Abstract: A biosensor and a method for manufacturing the biosensor. The biosensor comprises an insulative substrate (1), an electrode system (2, 3, and 4), a reagent, and an insulating layer (5). The insulating layer (5) covers a part of the electrode system (2, 3, and 4). Also, a closed region (6) without the insulation layer is formed at where the reagent is. The closed region (6) is provided with an enclosing border having no sharp corner. The reagent covers the closed region (6) and does not go beyond the enclosing border. The biosensor also comprises an assisted diffusion electrode (12). The use of the enclosing border having no sharp corner and of the assisted diffusion electrode (12) reduces the edge effect of the reagent, allows the reagent to diffuse uniformly at response areas of the electrodes, effectively controls the amount of reagent used, reduces product costs, and allows for simple manufacturing.
