Description

Biosensor having identification information and its measuring device {BIOSENSOR HAVING IDENTIFICATION INFORMATION AND DECIPHERMENT APPARATUS THEREOF}

The present invention relates to a biosensor, and more particularly, to a biosensor having identification information and a device for measuring the biosensor.

A biosensor is a means by which information can be obtained from a substance to be measured using biological or biological elements. Biosensors using biomaterials such as blood glucose and ketones as detection elements are excellent in sensitivity and response specificity and are used in a wide range of fields such as medical and pharmaceutical fields, process measurement of bio-industry, environmental measurement, and evaluation of chemical stability . For example, biosensors have been used for various self-tests such as blood sugar measurement, pregnancy diagnosis, urinalysis, and diagnosis of diseases.

In particular, a biosensor that operates by an electrochemical measurement method is mainly used for measurement of blood glucose. When a sample is introduced into a biosensor operating by an electrochemical measurement method, a target substance in the sample is oxidized by the catalytic action of the enzyme while reducing the oxygen or electron transfer mediator. The reduced oxygen or electron transfer mediator is oxidized by the voltage of the electrode to induce the change of electrons according to the concentration of the sample and quantify the change of the induced electron so as to measure the amount of the target substance.

Biosensors using an electrochemical measurement method may have variations in the area of the electrode or the amount of electrode material, and the measured values may vary for each biosensor due to such deviations. That is, a code is assigned to the biosensor for each production unit to reduce the deviation that may occur for each production unit, and the measurement device may identify the code and perform correction according to the corresponding code.

Conventionally, a user directly inputs a code assigned to a biosensor to a measurement device, but the user directly inputs the corresponding code to the measurement device, which causes inconvenience to a user and causes a malfunction due to an incorrectly input code.

In addition, as a method for identifying codes through a measuring device, a technology using bar code recognition, color detection, light transmittance detection, RFID, and the like has been proposed, but this technology increases the manufacturing cost of the biosensor and prevents the miniaturization of the product. There is a limit to increasing the power consumption of the measuring device.

Here, the identification shape generates at least one on / off signal to the measuring device so that the measuring device can calculate the identification information.
