Wearable Sensing’s DSI GSR are dry electrode sensors that have a wired connection directly to the DSI-24 or DSI Flex system. The sensors can are placed on the finger tips and used to detect sweat conductivity
GSR, or Galvanic Skin Response, is a technique for recording the variation in the electrical characteristics of the skin. Electrodes are typically placed on the finger tips, which then is used to measure skin resistance that varies with the state of sweat glands in the skin. Research has show that an increase in skin conductance is an indication of psychological of physiological arousal. It is important to note that an increase in arousal can be linked to both positive and negative stimuli, therefore, GSR is a representation of the intensity of arousal, and not the type of emotion.
