The Shimmer3 GSR+ (Galvanic Skin Response) unit provides connections and preamplification for one channel of Galvanic Skin Response data acquisition. Electrodermal activity (EDA) is the property of the human body that causes continuous variation in the electrical characteristics of the skin. Historically, EDA has also been known as skin conductance, galvanic skin response (GSR), electrodermal response . These responses are utilized as part of the polygraph or lie detector test. The Galvanic Skin Response (GSR), also named Electrodermal Activity (EDA) and Skin Conductance (SC), is the measure of the continuous variations in the.

Introduction Stress, better explained galvanic skin response sensor [ 1 ], is a response to particular events. It is the way our body prepares itself to face a difficult situation with focus, strength and heightened alertness. When we perceive a threat, our nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol.

The two current paths are along the surface of the skin and through the body. Active measuring involves sending a small amount of current through the body.

The amount of sweat glands varies across the human body, being highest in hand and foot regions — sweat glands per cm2. A correctly calibrated device can record and display the subtle changes.

Galvanic skin resistance GSR is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are galvanic skin response sensor placed about an inch apart, and the resistance recorded varies according to the emotional state of the subject.

Galvanic skin potential GSP refers to the voltage measured between two electrodes without any externally applied current. The circuit also contains a very galvanic skin response sensor resistance compared to the skin resistance that is in series with the voltage supplier and the electrodes.

As the voltage V is kept constant, skin conductance C can be calculated by measuring the current I flow through the electrodes.
