ARITHMETIC PROCESSING UNIT FOR MEASURING SKIN IMPEDANCE, PROGRAM, ELECTRONIC APPARATUS COMPRISING THE ARITHMETIC PROCESSING UNIT, AND SKIN IMPEDANCE EVALUATION METHOD
PROBLEM TO BE SOLVED: To provide an arithmetic processing unit capable of accurately measuring the skin impedance value of a horny cell layer in a wide range of skin conditions from a normal condition to a rough skin where the horny cell layer is peeled.SOLUTION: An arithmetic processing unit 401 causes an alternate signal originated by an AC signal generating circuit 410 to pass through the skin from an application electrode 201 and calculates the skin impedance value of a horny cell layer by subtracting a second impedance value generated in a granular layer and lower layers, from a first impedance value based on a signal detected from the skin.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】 例えば正常な状態から角層が剥がれた荒れ肌まで幅広い肌の状態で角層の皮膚インピーダンス値を精度よく測定できる演算処理装置を提供する。【解決手段】 演算処理装置４０１は、交流信号発生回路４１０により発せられた交流信号を印加電極２０１から肌に透過させ、肌から検出した信号に基づく第一のインピーダンス値から、顆粒層以下に生ずる第二のインピーダンス値を減算して角層の皮膚インピーダンス値を算出する。【選択図】図４
