Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method for measuring an electrochemical impedance spectrogram (EIS) in real time, the method comprising:
causing, by a processing device, a triangular excitation signal to be applied to a subject;
obtaining electrical parameter measurements in response to the triangular excitation signal;
measuring, by the processing device, an EIS of the subject based on the electrical parameter measurements, wherein the EIS of the subject is based on a ratio of a voltage spectrogram and a current spectrogram;
sampling the EIS of the subject at a plurality of frequencies that comprises multiple harmonics of a fundamental frequency of the triangular excitation signal; and
causing, by the processing device, the EIS to be provided to a workstation.
