ARITHMETIC PROCESSING UNIT FOR MEASURING SKIN IMPEDANCE, PROGRAM, ELECTRONIC APPARATUS COMPRISING THE ARITHMETIC PROCESSING UNIT, AND SKIN IMPEDANCE EVALUATION METHOD

摘要

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 4;COPYRIGHT: (C)2018,JPO&INPIT
