What is EmotiBit?

Scientifically validated, open-source alternative to research devices (e.g. Brain products, Empatica, Shimmer, BIOPAC)

EmotiBit is a wearable sensor for capturing high-quality emotional, physiological, and movement data. EmotiBit provides scientifically-validated sensing, making it an ideal tool for research. It's open-source (Arduino-compatible) and the data can be streamed wirelessly to any platform, enabling artists and makers to unlock new perspectives on biometric signals. EmotiBit is easy-to-use, so you can quickly integrate it into a class project. The data is 100% user-owned and can be directly recorded to the built-in SD card, empowering anyone to explore their own health and wellness without reservations about where that data might end up.

The fully open-source, cross-platform data visualizer software (Windows, Mac, Linux) is available to all EmotiBit users.

16+ biometric data streams: 

• PPG (3-wavelength) to derive heart rate, heart rate variability, respiration, oxygen saturation, hydration and (we believe) much more!
• EDA / GSR (electrodermal activity / galvanic skin response) reflecting sympathetic nervous system responses that are driven by cognitive and emotional arousal.
• 9-axis IMU (accel, gyro, mag) to derive movements, activity, gesture, rotation, and cardinal direction.
• Body temperature to assess health as well as emotional reactions.

EmotiBit Board - choose from Emo or MD 

What accessories are required?

EmotiBit boards require you to have a compatible Adafruit Feather, battery, microSD card + reader, and a micro USB cable.

We highly recommend you get an Essentials Kit to use EmotiBit out of the box, but we’re offering EmotiBit board-only options without a kit in case you already have all these parts or if you want to adapt the EmotiBit firmware to use another Feather or configuration.

We also have an Electrode Kit for folks who want spares and additional flexibility to use EmotiBit in research and other high-use settings.
