Abstract:

This paper presents a design for a fast measurement electrochemical impedance spectroscopy (EIS) system, which differs from the traditional single-frequency point calculation approach. The proposed system is capable of simultaneously measuring 23 frequency points within the frequency range of 1Hz-10KHz. Additionally, it has an impedance measurement range of 100\omega - 1M\omega. The experimental results demonstrate that the average MRE and PAE are both below 0.4% and 1°, with conditions of R=9940 \omega and C=1.02uF.

I. Introduction (Heading 1)

Electrochemical Impedance Spectroscopy (EIS) is a powerful sensing technique widely used in biotechnology to characterize implant-tissue interfaces [1]. It is also utilized for battery quality assurance and monitoring internal states like state of charge and state of health [2]. Unlike other electrochemical techniques, EIS applies sinusoidal signals to assess complex impedance over a frequency range, enabling deep understanding of electrochemical properties and differentiation of polarization processes [3].
