Identification of Irradiated Potatoes by Impedance Measurements

open access: yesAgricultural and Biological Chemistry, 1982
Measuring the impedance was found to be a highly reliable and practical technique for identifying irradiated potatoes. Impedance was measured by puncturing a potato tuber with a steel electrode and passing a 3 ~ 5 mA alternating current through it. Three parameters were determined: Z0/Z180 (impedance ratio at 5 kHz, 0 to 180 seconds after puncturing ...

Impedance Spectroscopy Based on Linear System Identification

open access: yesIEEE Transactions on Biomedical Circuits and Systems, 2019
Impedance spectroscopy is a commonly used measurement technique for electrical characterization of a sample under test over a wide frequency range. Most measurement methods employ a sine wave excitation generator, which implies a point-by-point frequency sweep and a complex readout architecture.
