发明名称 Apparatus for measuring skin moisture content and its operation method
摘要 <p>An apparatus for measuring skin moisture content, the apparatus including: an electrode unit comprising a reference (R) electrode, a current (C) electrode, and a measuring (M) electrode; an operational amplifier including an inverting input terminal that is supplied to a first voltage and connects with the R electrode, and an output terminal that connects with the C electrode; a switch controlling a connection between the output terminal and the C electrode; and a comparison control unit comparing the first voltage with a voltage at the output terminal, and controlling the switch to connect the output terminal and the C electrode when the voltage at the output terminal is less than or equal to a value that is acquired by multiplying the first voltage and a predetermined constant.</p>
