A portable tester for accessing human skin status quantitatively at home is reported. An interdigital electrode (IDE) that contacts directly with human skin is used as the sensing element. The electrode-skin model is simplified as a resistance and a capacitance in series. Using square wave signal for excitation, impedance of the IDE is measured in a charging/discharging way. During one measurement cycle, the response voltages at two excitation frequencies, i.e., 10 kHz and 600 Hz, are measured… CONTINUE READING
