Abstract
This paper presents the influence of the liquid infiltrated into the skin on the moisture measurement by a piston-type electrostatic sensor. The electrostatic sensor consists of the thin copper and silicone sheets and measures the voltage generated by which the sensor is contacted and released the skin. The voltage is changed by the skin moisture condition. In the experiment, the skin which the distilled water and 10 % glycerol liquid were infiltrated was measured by the proposed and commercial sensors. As a result, it was shown that the electrostatic sensor was influenced by the liquid.
