    摘要： The present invention relates to an electrochemical biosensor with improved hematocrit measurement accuracy for measuring blood glucose. According to the present invention, an electrochemical biosensor including a first electrode part for correcting a measured hematocrit value and a second electrode part for measuring a glucose concentration is effective in improving accuracy of a measured hematocrit value and in more improving accuracy of a measured blood glucose concentration using the measured hematocrit values for correction, because an insulation cover is made thinner than a working electrode and an auxiliary electrode, so that areas of a first working electrode and a first auxiliary electrode of the first electrode part exposed to a blood sample become equal; a distance between the first working electrode and the second working electrode becomes constant; and electrode areas are maintained constantly by the insulation cover even when a positioning error occurs during printing.

    摘要翻译： 本发明涉及一种具有改善血细胞比容测量精度的电化学生物传感器，用于测量血糖。 根据本发明，包括用于校正测量的血细胞比容值的第一电极部分和用于测量葡萄糖浓度的第二电极部分的电化学生物传感器有效地提高测量的血细胞比容值的精度，并且更有效地提高测量血糖的精度 由于绝缘覆盖物比工作电极和辅助电极薄，所以第一电极部分暴露于血液样本的第一工作电极和第一辅助电极的面积变得相等，因此使用测量的血细胞比容值进行校正。 ; 第一工作电极和第二工作电极之间的距离变得恒定; 并且即使在打印期间发生定位误差，电极区域也由绝缘盖保持恒定。
