Patent number: 8377272Abstract: Disclosed is an electrochemical biosensor measuring device which can be used together with an electrochemical biosensor. The biosensor measuring device comprises an electrical connection portion which is electrically connected with the electrodes of the biosensor upon the insertion of the biosensor there into, and a connector having a structure in which at least one light absorption or reflection path sequentially comprising a light emitter-production lot information identification portion-detector unit is provided to identify the production lot information recorded in the biosensor. The electrochemical biosensor measuring device can automatically identify the production lot information of the biosensor, encoded in the form of a hue or hole marks, upon the insertion of the electrochemical biosensor into the measuring device, thereby obviating the need to manually input the production lot information of the biosensor.Type: GrantFiled: February 26, 2008Date of Patent: February 19, 2013Assignee: i-SENS, Inc.Inventors: Keun Ki Kim, Moon Hwan Kim, Jae Hyun Yoo, Gang Cui, Hakhyun Nam, Geun Sig Cha

Patent number: 8314613Abstract: Disclosed are an electrochemical biosensor which comprises a production lot information identification portion, on which information is recorded in a magnetization mark, and a measuring device which can automatically identify the production lot information of the biosensor with the insertion of the electrochemical biosensor into the measuring device. The electrochemical biosensor and the measuring device thereof can record production lot information in the form of magnetization marks on an electrochemical biosensor strip and read the information as digital signals through a magnetoresistance sensor device, which can be mounted on the surface of a circuit board using Surface Mounted Technology (SMT). Without the need for a high-priced filter or a complicated calculation system, the magnetic detector system has a simple construction and realizes economic efficiency in the construction of the measuring device.Type: GrantFiled: February 26, 2008Date of Patent: November 20, 2012Assignee: i-SENS, Inc.Inventors: Gang Cui, Keun Ki Kim, Dong Hoon Han, Moon Hwan Kim, Hakhyun Nam, Geun Sig Cha
