Shimmer3 GSR+

Hardware Specifications

The Shimmer3 GSR+ (Galvanic Skin Response) monitors skin conductivity between two reusable electrodes attached to two fingers of one hand. Caused by a stimulus the sweat glands become more active, increasing moisture on the skin and allowing the current to flow more readily by changing the balance of positive and negative ions in the secreted fluid (increasing skin conductance).

The Shimmer3 GSR+ unit can also provide a photoplethysmogram (PPG) signal from a finger, ear-lobe, or other location on the body when adding an Optical Pulse probe.

The Shimmer3 GSR device is compatible with the iMotions EDA / GSR Module.

The iMotions EDA / GSR Module

Main features

The iMotions Electrodermal Activity / Galvanic Skin Response Module seamlessly integrates wired and wireless EDA /GSR devices from Shimmer, BIOPAC, and Empatica, so that you can conduct studies in both lab-based or real world settings, according to your chosen stimuli. The software allows you to easily quantify these moments of significant, increased arousal through automated peak detection and easy exporting of raw data, metrics, and visualizations.
