Impedance Measurements in the Presence of Type B Uncertainties

Odd Random Phase Electrochemical Impedance Spectroscopy (ORP-EIS) was introduced into the field of electrochemistry at the ELEC and SURF research groups. Due to the specific nature of these excitation signals, they expand the impressive capabilities of the well-known EIS technique. Different works have studied the effect of glucose based on EIS measurements. However, none of those works have studied the repeatability and reproducibility given the sensor brand or the sensor position. In this work, we will use ORP-EIS technique together and the best linear approximation, in order to investigate the precision of the impedance glucose measurements.
