Product Overview

The EmotiBit is a small device that allows you to stream 16+ data streams from the body, including PPG, EDA/GSR, 9-axis IMU, and body temperature.

  • What is EmotiBit?

    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.

    What accessories are required?

    EmotiBit boards require you to have a compatible Adafruit Feather, battery, microSD card + reader, and a micro USB cable. Want to take the guesswork out of ordering?

    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.

      What can you do with EmotiBit?

      Whether you're a researcher, developer, educator, artist, or just passionate about harnessing your own physiological data, the EmotiBit offers something for everyone! 

      Get inspired by the example projects in the product images.

      • Get immediate feedback about how cognitive and neural processes change your body’s physiology on a moment by moment basis.
      • Log your physical and psycho-emotional changes throughout the day.
      • Track changes in body temperature, blood oxygen levels, and much more to build a long-term record of your bio-data.
      • Create an audio-visual experience using your own biometric data. 
      • Data is accurately timestamped for synchronizing with other sensors/systems.
      • Use the simple data labeling feature built into the cross-platform EmotiBit data visualizer to leverage data science and machine learning and discover your bio-patterns.


      EmotiBit Board - choose from Emo or MD 

      What is the difference between the EmotiBit Emo and MD Boards?

        Product Name

        What's Included

      EmotiBit Emo         

      • PPG Sensor (3-wavelength)
      • EDA / GSR sensor (+AgCl snap electrodes)
      • 9-axis IMU (Accel, Gyro, Mag)
      • Temperature sensor (standard-grade)
      • Numerous derivative biometric streams
      • Finger strap

      EmotiBit MD

      • Everything on EmotiBit Emo
      • PLUS a medical-grade temperature sensor (thermopile) for sensing even more accurate body temperature

      The fully open-source, cross-platform data visualizer software (Windows, Mac, Linux) is included with all EmotiBit boards.

      Do I need a kit (sold separately)?

      You need several items in the Essentials Kit to use EmotiBit, including:

      • Adafruit Feather (HUZZAH32 or M0)
      • Lithium ion battery (400mAh sized to fit between the EmotiBit & Feather)
      • High-speed microSD card + reader
      • 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.
