  • Patent number: 8945369
    Abstract: There is provided a biosensor measurement system which can output a highly-precise measurement result even when an impact such as falling of the sensor occurs or the biosensor is an exposed sensor. An abnormal waveform detection electrode is provided in addition to electrodes for quantitative determination of a target substance. Therefore, when an impact is caused by such as falling of the sensor in a halt period where no voltage is applied in a voltage application algorithm, the abnormal waveform detection electrode can detect the impact. Further, also an exposed sensor can be detected by the abnormal waveform which is detected by the abnormal waveform detection electrode.

  • Patent number: 8475638
    Abstract: In a biosensor that detects introduction of a sample liquid into a specimen supply path using a detecting electrode, a means of improving accuracy of detection is provided. The biosensor has: an electrode system including measuring electrode, counter electrode, and detecting electrode on first electrically insulating support; specimen supply path for introducing the sample liquid; and reagent layer used for quantifying a substrate contained in the sample liquid. The means is characterized in that detecting electrode is spaced from measuring electrode by a distance sufficient for the sample liquid to sufficiently cover measuring electrode before the sample liquid reaches detecting electrode.
