Earables are ear-worn devices that offer functionalities beyond basic audio in- and output. We present the first version a new, open-source, Arduino-based earable platform called OpenEarable. It is based on standard components, is easy to manufacture and costs less than $100 per device at batch size 10. OpenEarable v1 comes equipped with a series of sensors and actuators: a 3-axis accelerometer and gyroscope, an ear canal pressure and temperature sensor, an inward facing ultrasonic microphone as well as a speaker, a push button, and a controllable LED.

OpenEarable is developed at the Karlsruhe Institute of Technology in Germany by the Pervasive Computing Systems group (TECO).
