GENEActiv is a medical-grade, wrist-worn accelerometer developed by Activinsights for high-resolution tracking of physical activity, sleep, and lifestyle behaviors in research and clinical trials.
Applications
- Clinical Trials: Used to assess treatment efficacy and provide real-world evidence in areas such as neurology (e.g., tremors, Parkinson’s), dermatology (e.g., scratching), and cardiology.
- Public Health Research: Ideal for large-scale longitudinal studies to objectively measure sedentary behavior and physical activity levels.
- Sleep Medicine: Provides high-quality data for diagnosing sleep disorders and assessing circadian rhythms.
Key Features & Specifications
- Sensor Capabilities: It captures raw, unfiltered tri-axial acceleration (up to 100Hz), environmental light intensity (lux), and near-body temperature.
- Battery & Storage: The device can record continuously for up to two months without charging, depending on the selected measurement frequency (e.g., 30 days at 20Hz).
- Durability: It is 100% waterproof and designed for 24-hour wear on the wrist, arm, or leg.
- Data Format: Outputs raw data in an open .bin format, which can be converted to .csv or analyzed using specialized tools like R, MATLAB, or the Activinsights Sleep Toolkit.
