Patent ID: 11953532
Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. An electrochemical impedance spectrogram (EIS) measurement system, comprising:
a working electrode configured to provide a triangular excitation signal to a subject;
a counter electrode configured to measure an electrical parameter in response to the triangular excitation signal; and
a processing device configured to obtain an EIS of the subject based on the triangular excitation signal and the measured electrical parameter, wherein the EIS of the subject is based a ratio of a voltage spectrogram and a current spectrogram, and wherein the processing device is further configured to sample the EIS of the subject at a plurality of frequencies that comprises multiple harmonics of a fundamental frequency of the triangular excitation signal.
