Biosensor structure for measuring specimen and method for measuring specimen by using the same

A biosensor structure for measuring a specimen, the biosensor structure comprising:

• a lower plate, in which a working electrode and a reference electrode that are electrodes for measuring a specimen, and at least one recognition electrode for recognizing the specimen are disposed in an insulation substrate, the working electrode and the reference electrode are spaced apart from each other in a lengthwise direction of a specimen insertion passage, a working boss that is a boss of the working electrode and reference bosses that are two bosses of the reference electrode are alternately arranged in a part corresponding to the specimen insertion passage, and a ratio of an area of the working boss and an area of the reference bosses is 1 or more, at least one recognition electrode is disposed adjacent to the working electrode or the reference electrode and is spaced apart from the working electrode and the reference electrode in parallel, and a recognition boss that is at least one boss is disposed at a part corresponding to the specimen insertion passage;
• a middle plate having the specimen insertion passage, wherein an enzyme compound is inserted into the specimen insertion passage, and
• an upper plate, in which an insertion hole for inserting the specimen and a discharge hole for discharging air are formed at parts of an insulation substrate, which correspond to the specimen insertion passage.

A system for measuring a specimen, the system comprising:

• a collection device including a collection unit configured to collect a specimen, and a filter configured to remove interference materials that are obstructions in measuring the specimen collected by the collection unit;
• a biosensor having an electrode structure, in which a working electrode and a reference electrode that are electrodes for measuring the specimen, from which the interference materials have been removed, and at least one recognition electrode for recognizing the specimen, from which the interference materials have been removed, are disposed in an insulation substrate, the working electrode and the reference electrode are spaced apart from each other in a lengthwise direction of a specimen insertion passage, a working boss that is a boss of the working electrode and reference bosses that are two bosses of the reference electrode are alternately arranged in a part corresponding to the specimen insertion passage, and a ratio of an area of the working boss and an area of the reference bosses is 1 or more, at least one recognition electrode is disposed adjacent to the working electrode or the reference electrode and is spaced apart from the working electrode and the reference electrode in parallel, and a recognition boss that is at least one boss is disposed at a part corresponding to the specimen insertion passage;
• and
• a measurement device configured to, when the specimen, from which the interference materials have been removed through the collection device, is inserted into the biosensor after a strip of the biosensor is inserted, measure the specimen, from which the interference materials have been removed, based on a specimen measurement signal received through the working electrode and the reference electrode.

A method for measuring a specimen, the method comprising:

• collecting a specimen by using a collection unit, and removing interference materials that are obstructions in measuring the specimen, from the collected specimen, by using a filter;
• causing the specimen, from which the interference materials have been removed, to contact a biosensor;
• and
• measuring a response signal to the specimen, from which the interference materials have been removed, by applying a specimen measurement signal to a working electrode and a reference electrode of the biosensor, when a contact of the specimen, from which the interference materials have been removed, is recognized by at least one recognition electrode of the biosensor,
• wherein the working electrode and the reference electrode are spaced apart from each other in a lengthwise direction of a specimen insertion passage, a working boss that is a boss of the working electrode and reference bosses that are two bosses of the reference electrode are alternately arranged in a part corresponding to the specimen insertion passage, and a ratio of an area of the working boss and an area of the reference bosses is 1 or more, and at least one recognition electrode is disposed adjacent to the working electrode or the reference electrode and is spaced apart from the working electrode and the reference electrode in parallel, and a recognition boss that is at least one boss is disposed in a part corresponding to the specimen insertion passage.
