NIRxWINGS2 - Physiological Sensor Module
The NIRxWINGS2 module for peripheral physiology measurements extends the NIRSport2. It comes with sensors for respiration, ExG, electrodermal activity (EDA -frequently referred to as Galvanic Skin Response), temperature, and PPG pulse oximetry (PPG). All signals are fully synchronized and in one data stream in Aurora.

Wireless data transfer allows participants to move freely while data is both stored on the device and streamed in real time. The NIRSport2 platform and the NIRxWINGS2 provide a combined LSL stream, ensuring seamless integration for multimodal research.
NIRxWINGS2 Advantages
The ideal in fNIRS research is that we measure only the evoked hemodynamic response. In reality, non-evoked, systemic activity is also present. To ensure we completely isolate the metabolic brain activity (i.e., HbO and HbR) due to the task we are interested in, we can measure peripheral physiological data (e.g., heart rate, respiration, tonic/phasic skin conductance, SpO₂). These additional signals help explain more variance in the fNIRS signal, improving research outcomes.
With NIRxWINGS2, you can move outside the lab into complex, dynamic, and multi-sensory real-world environments to conduct Systemic Physiology-Augmented fNIRS (SPA-fNIRS). The system enables new experimental paradigms and the creation of high-quality research databases.
