A method of skin conductance response measurement that is robust again contact area change

摘要

A method for measuring an SCR(Skin Conductance Response) robust against a contact area change is provided to apply the SCR to wearable computing application and ubiquitous computing application. A method for measuring an SCR includes the steps of: measuring a conductive current and a capacitive current from a first electrode and a second electrode at the same time; and estimating a conductive current per a unit contact area by removing a contact area parameter from the conductive current and the capacitive current. The SCR is measured by setting a contact area of the second electrode to be larger than the contact area of the first electrode or to be relatively uniform in comparison with the first electrode. The first electrode is a metal plate which is in contact with an end of a finger of a subject. The second electrode is inserted into the finger.
