EPFL Lausanne Android Meets IoT Event Highlights SeizureGuard, Set to Integrate Spresense in Next Phase

Jéssica Paiva Santos, March 5, 2025

On February 25th, 2025, the Embedded Systems Lab (ESL) at the École Polytechnique Fédérale de Lausanne (EPFL) hosted the Android Meets Internet of Things (IoT) event, gathering students from the university’s MSc program to present a range of projects that combine Android applications with IoT technologies.

One of the standout projects was SeizureGuard, developed by Francesco Poluzzi and François Dumoncel. This app uses Android devices to detect epileptic seizures in real-time by analyzing EEG signals with an AI model running directly on the phone. It can immediately alert caregivers, record and replay EEG data, and adjust the AI model based on the patient's specific needs.

Looking ahead, SeizureGuard is set to integrate Sony’s Spresense microcontroller in its next phase. This integration will allow the app to generate synthetic EEG signals on Spresense, with tunable parameters including noise levels, the presence of artifacts, and more. The data will be automatically generated and sent in real-time via a Bluetooth link to the Android app. This will create a closed-loop framework for testing and evaluating wearable seizure detection methodologies, providing a more robust environment for refining the system's performance.

The event also featured several other interesting projects, including:

Second place: “AcroYoga” by Ismael Frei and Barbara de Groot: This app helps track the progress of AcroYoga practitioners, estimating how well they perform various poses. It also allows users to use smartwatches to take photos on another device during exercises.

Third place: “Fitness Drone” by Julian Donevsky, Océane Maroux, and Robin Carlet: The app controls a Parrot Anafi drone, enabling it to follow users during activities like biking or running. It uses GPS to keep a constant distance from the user, records footage, and offers a cloud-based gallery along with a manual mode where the phone acts as a joystick.

After the presentations, attendees were able to interact with the project teams and see the ideas come to life through live demos. The evening ended with an awards ceremony, where the most innovative projects were celebrated, with SeizureGuard standing out for its potential in the health tech space.

The integration of Spresense into SeizureGuard marks a step forward for the project, providing the students with powerful hardware to refine their ideas. The collaboration between Sony’s Sensing Solution University Collaboration Program (SSUP) and EPFL continues to give students valuable opportunities to work with advanced technologies and contribute to impactful solutions.
