Fig. 4: Human subject study on impedance measurement of healthy cutaneous tissues and lesions.
From: Wearable battery-free chip-less patch for bioimpedance measurement of cutaneous lesions
a Bioimpedance measurement of mole and skin using the patch on various parts of body, micrograph of a pigmented lesions and location of electrodes, and a flowchart of measuring the bioimpedance of moles and healthy skin. b, c Magnitude and phase of reflection coefficient measured by the patch on mole and on healthy skin. d Change in reflection coefficients and resonance frequencies at different locations on human skin. e, f Change in the capacitance and resistance was measured on mole and on the skin for ten subjects. g Comparison of Impedance measurement on different subjects with the Nevisense device.
