EDA artifacts can come from the electrodes used to collect EDA data [1]–[3]; examples being:
Inconsistent pressure of the electrode to the skin
Physical activity (such as pressure or movement)
Arbitrary changes made to securing the device
Contextual/ambient factors (such as humidity, temperature, etc. Anything that can cause excessive EDA signals beyond a device's detection abilities)
Overloading a device that records EDA signals is a special kind of artifact called "bridging" or "saturation". [4]
