3.1.3 Electrodermal Activity (EDA)
Figure 19: EDA sensor.
Our EDA sensor is capable of accurately measuring the skin activity with high sensitivity
in a miniaturized form factor. The low-noise signal conditioning and amplification circuit
design provides optimal performance in the detection of even the most feeble
electrodermal skin response
How to connect your sensor to your biosignalsplux
EDA sensors can be connected to any of the available analog inputs of your biosignalsplux
device (see 2.3.2 Analog Inputs).
This sensor does not require an additional reference electrode.
How to configure your sensor in OpenSignals (r)evolution
Open the OpenSignals (r)evolution device manager and select the device you have your
EDA sensor connected to. Select the channel of your EDA sensor and activate this channel
for signal acquisition by clicking on the circle in the channel field (must be blue).
OpenSignals (r)evolution offers two modes that are designed for different applications for
EDA sensors that can be selected in the dropdown menu which can be accessed via the
channel field (click on the arrow in the channel’s field that appears when you hover over
the channel’s field).
The EDA option is designed to work with applications where the EDA sensor is placed, for
example, on the hand of the subject. If you plan to use the EDA sensor on the arm of a
subject, we recommend selecting the EDA.ARM configuration to ensure high quality data
acquisition.
