Electrodermal activity (EDA) is a sensitive index of sympathetic nervous system activity. [] Key Result An important result presented in this paper is evidence that the distal forearm is a viable alternative to the traditional palmar sites for EDA measurements. Our device offers the unprecedented ability to perform comfortable, long-term, and in situ assessment of EDA.
Design and Evaluation of an Electrodermal Activity Sensor (EDA) With Adaptive Gain
TLDR
The proposed circuit has shown comparable results to those obtained with a reference sensor, obtaining a mean correlation coefficient of 0.967, and proved to have superior performance in cases where the reference sensor would saturate, allowing the dynamic adaptation of the measurement range.
Delineating the Operational Envelope of Mobile and Conventional EDA Sensing on Key Body Locations
TLDR
A validation experiment used startle stimuli to instantaneously arouse the sympathetic system of n=23 subjects while sitting to reveal that precise measurement of small EDA responses on the fingers and palm is feasible either with conventional or mobile EDA sensors.
Obimon: An open-source device enabling group measurement of electrodermal activity.
TLDR
It is concluded that the Obimon device presented here is a valid and feasible tool for collecting EDA in single or multisubject environments.

Dry Electrode Optimization for Wrist-based Electrodermal Activity Monitoring
TLDR
This study focuses on identifying an optimum dry electrode configuration for monitoring EDA from the wrist and hypothesized that parameters like electrode material, interelectrode distance and anatomical location of measurement influence the dry electrode design for EDA detection.
Electrodermal Activity Sensor for Classification of Calm/Distress Condition
TLDR
A new and unobtrusive wearable monitoring device based on electrodermal activity (EDA) to be used in health-related computing systems and shows around 89% accuracy when distinguishing calm condition from distress condition.
Bilateral comparison of traditional and alternate electrodermal measurement sites.
TLDR
The fingers and the feet are the most reliable locations to measure from, followed by the wrists, while response latency was the shortest on the fingers while it was the longest on the lower body.
