An accelerometer is also included in the sensor, so that you can correct the EDA recordings for movement. The EdaMove uses the exosomatic method, by applying a 0.5V direct current, and samples with 32 Hz. The system consists of a small device that can be attached to the arm, and two electrodes to measures EDA at the palms of your hand. Feel free to edit this list and include any other wearable devices you know of.Ī system that I am currently testing is the MoviSens EdaMove. Philips Respironics (unclear how GSR integrates)ĭisclosure: I work for iMotions.Samsung Simband (not commercially available yet, it seems).Watch-like devices, with electrodes placed on the wrist: Moodmetric ring (have not looked at this).Shimmer, integrated in iMotions for multimodal research.Wearable devices supporting electrodes on the palms/fingers: Of course, not all experiments allow to place electrodes there, in which case electrodes on the wrist might still be worthwhile exploring. Measurements on the wrist are much less sensitive, as shown in Seanny123's answer in case of the Empatica E4. Glands varies markedly across the body, being highest on the foreheadĪnd cheeks, the palms and fingers as well as on the sole of the feet.įor wrist-worn devices this means ideally you place the electrodes on the palms or fingers. Our body has about three million sweat glands. One key thing to point out is (emphasis added): IMotions has a pocket guide on GSR targeting a layman audience (believe the PDF you can request might be more up-to-date).
