- Abstract:
- The paper briefly considers the metrology of electrochemical impedance spectroscopy (EIS) in time-frequency domain for analysis of nonstationary processes in liquids and organic tissues. In particular, the application of normalization operator to satisfy the stationarity condition in impedance calculation is discussed. It introduces new measurement scales as inverse functions of time func(t)E-1 and frequency-time func(f, t)E-1 or operates in dimensionless units. Such normalization shifts the focus of EIS from electrochemical test systems to external excitations affecting samples. This provides universality required for characterization of chemical, biological and biophysical interactions of different nature. Reproducible calibration of EIS devices for standardization of such measurements is described. The discussed approach is exemplified by differential EIS measurements in thermostabilized system with excitation of fluidic samples in thermal and optical way.
