Swimtraxx is a Belgian sports technology start-up. They have developed the Swimtraxx One, an activity tracker for swimmers. The device is mounted on the swimming goggles. It measures heart rate next to many other biomechanical parameters in real-time. The heart rate is measured by a PPG sensor at the temple of the head.

The aim of this project is to develop a real-time algorithm that automatically extracts the heart rate from the PPG signal acquired from the wearable device. All available signals will be real signals acquired from swimmers during their training. As an extra restriction, the algorithm should be able to run on the microcontroller of the device.

We have projects in Gent, Leuven and Antwerpen.
