The Senstream Researcher Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. The app is designed to record physiological signal data, but not to make medical decisions.

Electrodermal activity (EDA, aka GSR), ECG, PPG, temperature and motion, captured from a single, user friendly device with long battery life.

Electrodermal Data:
Our initial product is the first ring form factor device that captures electrodermal activity with lab quality, enabling new types of research.

ECG and/or Pulse:
Capture electrocardiograph (ECG) and/or photoplethysmograph (PPG) data, depending on the specific needs of a study or application.

Temperature and Motion:
Capture temperature data from the finger, and contextualize physiological data with motion data captured by the Research Ring.

Mobile and Cloud Apps:
Start capturing data with just a ring and mobile app, which seamlessly connects to the cloud. BIOPAC integration offers powerful tools.

Bold Vision:
The Senstream roadmap, supported by a rich patent portfolio, leverages the convenience and unique physiology of the finger. Stay tuned!

What’s New

Version 1.0.1

The Sessions tab has been rewritten to better show your list of sessions stored on device and in Senstream Cloud.

Session Detail includes a new and improved chart view. Switch between signal types, toggle peak annotations, change zoom levels, rename your session, and export your session data.

The temperature signal is now being recorded in Celsius.

The app will let you know when new firmware is available for rings paired with your app.

Tap on a ring to view its detail, upgrade its firmware, calibrate, and set it into “Ship Mode”. Once the ring is in this new mode, place it on its charger to wake it up again.
