Abstract:
A disposable glucose biosensor which is insertable and removable from a device body, said disposable glucose sensor comprisingan upper plate, a lower plate, a space formed between the two plates for housing a sample therein, a layer for fixing the two plates together, an opening for admitting the sample at a first end of the biosensor, a working electrode, a counter electrode fixed relative to the working electrode, the working electrode having oxidoreductase thereon, the lower plate including an insulating base having the working and counter electrodes thereon, and a sensor insertion signal terminal also formed thereon at an opposite end to the first end for interconnecting, upon insertion of the biosensor into the device body, two input terminals of the device body to allow power to flow between the two input terminals through the sensor insertion signal terminal and to the working electrode and said sensor insertion signal terminal being located with output terminal extensions of the working and counter electrodes also at said opposite end and being electrically insulated from the working and counter electrodes while being separated from the space for housing the sample.
