Abstract
An electrode refreshing arrangement of a biosensor includes a constant reverse bias voltage arranged to be supplied between a working electrode and a reference electrode, so as to thereby refresh the working electrode, that is, to remove the disturbance film or substance formed on the surface of the working electrode as a result of the enzyme reaction, thus reviving the activity of the working electrode.
