Each coating includes a base portion and a plurality of unit cells extending from the base portion. The unit cells combine to form a microstructure on an outer surface of the coating. Dimensions and spatial arrangements of the unit cells can be controlled to provide controlled variations along a contour defined by the microstructures, so that the contour conforms to ridges in the skin surfaces of multiple users. This increases electrical conductivity between the skin surfaces and the conductive coating, thereby enhancing electrical contact between the user and the electrodes covered by the coating.

Use of the turntable enables a rotational orientation of the electrodes to be adjusted so as to achieve maximum available area overlap with eccrine glands located in the skin of a user in contact with the electrodes. This maximum available area overlap may provide a best available S/N ratio for an EDA signal generated based on electrode current transmission through the user's skin.
