In March 2025, the French Alternative Energies and Atomic Energy Commission (CEA) launched AUDACE, a €40 million research program under the France 2030 initiative, bringing together over 80 academic partners across France to support roughly ten projects aimed at breaking technological barriers. One key project, BrainSync, led by CEA-Leti, focuses on developing a brain-computer interface (BCI) therapy for post-stroke rehabilitation.
The CEA’s WIMAGINE® BCI implant has already enabled two world firsts: in 2019, a tetraplegic patient controlled a four-limb exoskeleton, and in 2023, a paraplegic patient regained natural walking by pairing the implant with spinal cord stimulation developed by EPFL, CHUV, UNIL, and ONWARD Medical. Building on these advances, Serpil Karakas, software lead at CEA-Leti, is now engineering a neurorehabilitation platform for stroke survivors suffering from upper-limb mobility and motor deficits. Neurotechnology researcher Lucas Struber confirms that CEA-Leti, Grenoble Alpes University Hospital, and Saint-Étienne University Hospital have filed for regulatory approval to launch a clinical trial.
The therapy establishes a real-time link between motor intent detected in brain activity and corresponding sensorimotor feedback—via electrical stimulation, robotic assistance, or virtual feedback—with the goal of reinforcing neural circuits and promoting functional recovery through neuroplasticity. In addition to French government support under AUDACE, the work is funded by a European Innovation Council grant from Horizon Europe.
