BIOPAC
Revolutionary Multi-Modal Sensor Ring Delivering Lab-grade Physiological Data

The Research Ring from BIOPAC is a multi-modal wearable sensor system designed for real-time, high-quality physiological data collection in both laboratory and field research environments. This innovative platform allows researchers to customize the ring's configuration with up to four swappable sensor modules, each targeting specific physiological signals.

Whether you're studying autonomic activity, emotional responses, stress levels, or cognitive load, the Research Ring provides a compact, comfortable, and wireless solution that doesn't compromise on signal fidelity. The device interfaces seamlessly with BIOPAC’s data acquisition systems, making it ideal for multimodal experiments involving EEG, fNIRS, ECG, respiration, and more.

Multi-Modal Measurements

The Research Ring allows researchers to measure a variety of different physiological metrics at the "tip of a finger". Current and upcoming sensors measure:

  • EDA (Electrodermal Activity) – Skin conductance for sympathetic arousal
  • PPG (Photoplethysmography) – Heart rate and pulse
  • ECG (Electrocardiography) - Electrical heart activity
  • Temperature – Skin surface temperature
  • Accelerometry – Movement and activity detection
  • Others in development – e.g., haptic feedback, environmental sensors

Research Ring Unboxing and Set Up Tutorial

Key Features

  • Wearable, comfortable ring form factor
  • Modular sensor integration – up to four sensors per ring
  • Wireless transmission – no cables, full freedom of movement
  • Real-time data streaming into AcqKnowledge or mobile apps
  • High signal quality designed for research-level accuracy
  • USB charging cradle for simple power management
  • Compatible with BIOPAC’s Smart Center platform for sensor management and synchronization

Applications

The Research Ring is ideal for studies in:

  • Emotion and stress research
  • Human factors and usability testing
  • VR/AR interaction studies
  • Ambulatory monitoring
  • Neuroergonomics
  • Wearable cognition and performance
  • Multimodal psychophysiological experiments

Its discreet and unobtrusive form makes it particularly suited for naturalistic and ecologically valid research, where traditional wired sensors may interfere with behavior or realism.
