Calibration currents for different concentrations of glucose based on five different sensors. Response is measured at 0.5 V with respect to the Ag/AgCl (reference) electrode. The current signal is generated by averaging current values from 20 to 55 s after each successive addition of 0.75 mg/dl glucose. (A) Calibration currents for pillar electrodes with circular cross section. (B) Calibration currents for pillar electrodes with square cross section.
