Empatica -Model E4 -Medical-grade Biometrics Wearable Device

CE-medical certified in the EU, pharmaceutical companies, government agencies, and research institutions are using the E4 in trials for collecting physiological data relevant to drug, healthcare, device, and algorithm development.

• Unobtrusive monitoring : Record in the lab or at home with no hassle
• Clinical quality observation : Obtain accurate and precise physiological data
• Your data anywhere : Easily access and view your raw data with our secure cloud platform
• Develop your own apps : Use our developer tools to build your own app and access real-time E4 data

The E4 is equipped with sensors designed to gather high-quality data. It is the only wearable on the market to combine EDA and PPG sensors, simultaneously enabling the measurement of sympathetic nervous system activity and heart rate.

• PPG Sensor : Measures Blood Volume Pulse (BVP), from which heart rate variability can be derived
• 3-axis Accelerometer : Captures motion-based activity
• Event Mark Button : Tags events and link them to physiological signals
• EDA Sensor (GSR Sensor) : Measures the constantly fluctuating changes in certain electrical properties of the skin
• Infrared Thermopile : Reads peripheral skin temperature
• Internal Real-Time Clock : 5ppm high accuracy time reference
