摘要：
An apparatus for measuring skin moisture content in a users skin is provided. The apparatus may include a signal supplier to generate an out-of-phase signal from a voltage signal obtained from the users skin and an in-phase signal from the voltage signal, a susceptance measurement unit to measure the susceptance of the voltage signal by synchronizing the voltage signal and the out-of-phase signal received from the signal supplier, a conductance measurement unit to measure the conductance of the voltage signal by synchronizing the voltage signal and the in-phase signal, and an output unit to output sweat gland activity information of the user based on the measured conductance and skin moisture content information of the user based on the measured susceptance.
