Hardware Specifications

BIOPAC BIONOMADIX 2CH GSR/EDA Amplifier

The BIOPAC BIONOMADIX 2CH GSR/EDA Amplifier is a wireless unit that is an add-on to the wired BIOPAC MP150 device for measuring skin conductance, also known as Electrodermal Activity (EDA) or Galvanic Skin Response (GSR). The module pair emulates a “wired” connection from the subject to computer, with all the benefits of a fully-wireless recording system. These units interface with the MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications and supporting acquisition of a broad range of signals and measurements.

The BIONOMADIX 2CH GSR/EDA Amplifier is compatible with the iMotions EDA/GSR Module and can also be used to capture Photo Plethysmogram (PPG) signal data in order to perform Heart Rate Variability (HRV).

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.
