The Obi device

A small wearable sensor for electrodermal activity (EDA): the changes in the skin's conductance that follow arousal and stress.

What it measures

  • Skin conductance (EDA), in microsiemens (µS), four times a second
  • Movement, so moments of motion can be told apart from real changes
  • Electrodes on the fingers; the sensor rests on the hand

How it connects

  • Bluetooth Low Energy, straight to the browser: no app to install
  • Works in Google Chrome on Windows and Apple computers and on Android devices
  • Firmware can be updated over the air
