The Qubit GSR (Galvanic Skin Response) Sensor measures the psycho-galvanic reflex. This reflex generates a change in skin conductivity during periods of stress, excitement, or shock and is used as a measure of sympathetic nervous system activity. This sensor monitors the conductivity of the skin between two disposable tab electrodes that are placed on two adjacent fingers of one hand. This sensor can monitor both rapid and slow changes in skin conductivity, making it ideal for studies involving shock, arousal, and biofeedback.
