Biosensor for measurement of alcohol concentration and method of manufacturing biosensor, and alcohol measurement device using biosensor

摘要

The present invention relates to a biosensor for measuring an alcohol concentration capable of measuring an alcohol concentration by reacting with an alcohol in a gaseous state and a strip sensor for measuring an alcohol concentration in the form of a strip capable of measuring the alcohol concentration in the gas phase occurring during human breathing And a breathalyzer using the biosensor for measuring the alcohol concentration.;Conventional alcohol biosensors using an electrochemical measurement method require a liquid sample, and a drinking meter using a gas sensor using an alcohol-reactive oxide semiconductor has disadvantages of lacking clarity and reliability in alcohol concentration measurement, There was a disadvantage of malfunction.;The present invention relates to a method for manufacturing an electrode assembly, in which a paste for electrode manufacturing is screen-printed and comprises an insulating substrate (1) for constituting a unit sensor element, a conductive line printed on the insulating substrate (1) An electrochemical device composed of an electrode part through which a reaction current flows when reacting with alcohol and is printed on the conductive line and the connection pad 2 and an insulating layer 6 insulating the entire surface excluding the electrode part, An enzyme immobilization layer 7 for printing an enzyme paste on the electrode part of the enzyme immobilization layer 7 and reacting with the alcohol and an outer membrane 8 printed on the entire surface of the electrode part on which the enzyme immobilizing layer 7 is formed, Sensor is manufactured, and a drinking meter is manufactured by using it, thereby solving the above conventional problems.
