Method for sensing the concentration of glucose in biological fluids

摘要

Glucose sensing apparatus for use in biological fluids comprising an electrode and a voltage source connected to the electrode to cause a current to flow therethrough, in which the voltage applied to the electrode is varied in a sweep ranging from a first limit to a second limit and back toward the first limit, and the current at the electrode is integrated with respect to time during at least a portion of the voltage variation selected to produce a total charge sensitive to glucose concentration and relatively insensitive to other components in the fluid; alternatively the current is measured at a point in a specific region of the voltage variation.
