Determination of Electrical Parameters for Skin during Galvanic Skin Reflex from Continuous Measurement
نویسنده
چکیده
The skin impedance is well various and changeable rapidly, so it is not easy to measure precisely the all frequency characteristics(l). In order to measure the all frequency characteristics, there are two methods as follows. One is multi-frequency points measuring method and the other is the fast fourier transformation (FFT) method from the response in time domain. However, the former demands very complicated device and the latter is not enough short time period of measurement for GSR. This report describes the method which uses the characteristics of skin impedance and determines perfectly and continuously the all frequency characteristics from the measuring skin impedance of one frequency point. This method is convenient to apply for the case that an impedance changes rapidly in short time as GSR course.

Sensitive and Accurate Measurement Environment for Continuous Biomedical Monitoring using Microelectrodes
This paper presents a new non-invasive biomedical monitoring of selected psychosomatic processes. The proposed method measures human skin conductivity using the interdigitated array (IDA) microelectrodes, which allow continual monitoring and analysis of complicated physiological, pathophysiological, and therapeutic processes. The main goal is monitoring of psycho-galvanic reflex of the human sk...

The psycho-galvanic reflex is a decrease in the electrical resistance of the skin which occurs in response to a wide variety of stimuli. The physiological basis of this autonomic measure, known also as the galvanic skin response or electro-dermal response, has not yet been fully elucidated. There are two principal theories accounting for the phenomenon. The vascular theory, proposed by Fire (18...
