What is and what affects Electrodermal activity (EDA)?


Electrodermal activity is an output of the sweat glands on a microscopic level. It serves as an indicator for emotional stimulus, and can be affected by various factors.

Several components can result in an elevated EDA, such as anything that makes you sweat (sports, excitement, stress). We’re analyzing characteristic EDA signatures during seizures so we can decrease the number of false alarms and finetune Embrace’s algorithm.

Electrodermal activity is affected by skin hydration, placement and other biochemical factors. EDA can fluctuate based on daily water intake and with certain medications. EDA is part of our algorithm but does not take precedence over other factors, given its susceptibility to variation.
