Based on popular demand, Empatica's engineering group approved the modification of the E4 from a semi-permanent screw-on electrode to snap-on architecture. We're now offering a solution to make E4 compatible with traditional EDA electrodes for use in the lab.


The new band accepts a pair of silver plated brass button electrodes which can be easily switched out for lead-wire extensions. The extensions allow researchers to use E4 with a variety of traditional EDA electrode configurations. This enables the use of E4 in a wide range of research settings with configurations for palmar skin conductance measurement or the use of gelled electrodes secured under the band.
