Biosensor having identification information and apparatus for reading identification information of biosensor
A biosensor is provided, including an identification information recording unit having identification information of the biosensor recorded thereon, where the identification information recording unit is a color tag that is attached on the biosensor and indicates the identification information by color, chroma of color, or arrangement pattern of colors. An apparatus for reading identification information of a biosensor is provided, including: a biosensor sensing unit detecting the biosensor; a light-emitting unit emitting light on an identification information recording unit when the biosensor sensing unit detects the biosensor, the identification information recording unit having the identification information of the biosensor recorded thereon; a light-receiving unit that receives the light emitted from the light-emitting unit, and reflected or refracted by or passing through the identification information recording section; and an identification information reading unit analyzing the light received by the light-receiving unit and reading the identification information of the biosensor.
1. An electro-chemical biosensor comprising:
an electro-chemical biosensor element comprising electrodes and configured to obtain measurement results by reading current applied to the electrodes upon introduction of a blood sample; and
an identification information recording unit comprising two or more non-overlapping color segments on a surface of the electro-chemical biosensor element, each of the color segments presenting color on a single layer, the color segments being arranged and configured so that a combination of respective colors of the color segments regardless of shapes of the color segments provides optically readable identification information of the electro-chemical biosensor element;
wherein the optically readable identification information comprises any one or any combination of a type of the electro-chemical biosensor element and a correction code used to correct the measurement results obtained by the electro-chemical biosensor element.
2. The electro-chemical biosensor of claim 1 , wherein the two or more color segments each comprise a chroma of color.
3. The electro-chemical biosensor of claim 1 , wherein the identification information recording unit comprises a color tag attached to the electro-chemical biosensor element; and
the color tag comprises the two or more color segments.
4. The electro-chemical biosensor of claim 1 , wherein each of the color segments is configured to present the color on the single layer independent of the measurement results obtained by the electro-chemical biosensor element.
