EDA-Analysis (EDA: Electro Dermal Activity)
The electro dermal Activity shows changes in the skin resistance which are triggered by the stress of
the person. Short changes (e.g. emotional stress) and also fluctuations with long duration will be
measured.
fig. 7-28: EDA-Analysis
The EDA analysis smoothes the raw data signal by averaging the value (every 250ms a new average
value is formed). The determined values are used as conductances (unity: Siemens [S]) in a
represented curve.
The electro dermal activity (from dermis: skin) is used for the analysis of the electric phenomena of the
skin. The electro dermal activity is influenced by the rise of the Sympathikotonus which come with
emotional reactions. These also coincide with increased sweating which causes a drop in the electrical
resistance of the skin.
