Artificial Skin Characterization Using Galvanic Skin Response Data

摘要

Electrodermal activity (EDA) recording of skin, popularly used in forensic investigation, is a viable technology currently explored in widespread applications, like robotics, wound characterization, along with a variety of others. Although EDA technology is simple, low in cost, and easy to use in clinical setting, its reliability and accuracy can still be challenged. In order to accurately measure galvanic skin response (GSR) signal and free from response to human emotion, the study used synthetic skin. Major avenues for this research include analyzing the effects of the application of alcohol and water, application of topical compounds, various sizes of skin, and placement of electrodes. Electrical conductance on natural skin increases due to sweat expulsed through sweat glands and this provides a sensitive and non-invasive representation of sympathetic nervous activity. Artificial skin doesn't contain sweat gland activity, but it is known for its baseline conductance which alters when there is a change to the structure. By developing a thorough understanding of artificial skin and its characteristics, it validated the reliability of GSR readings and therefore the effectiveness of measuring devices with interference of additional factors.
