1. A method for sensing the concentration of glucose in biological fluids comprising the steps ofapplying a variable voltage to an electrode to cause a current flow therethroughsweeping said voltage over a range in a first direction from a first limit to a second limit and in the reverse direction back toward said first limit, andintegrating current at the electrode with respect to time during a period including at least a portion of said sweep in both directions selected to produce a total charge sensitive to glucose concentration and relatively insensitive to other components in the fluid.
