MagnetoEncephaloGraphs (MEGs) are the most accurate instruments for recording neuronal activity. We believe that quantum sensors based on optical pumping of helium (helium OPMs) will pave the way for a new era of MEG, opening the access to richer recordings, increased patient comfort, at much more affordable prices than current cryogenically-cooled sensors.
Mag4Health, our startup, currently incubated by CEA-Leti in Grenoble, pioneers this new generation of MEG, and works towards its industrialization and sale.
Our MEG systems rely on the only OPMs working at room temperature, without any heating or cooling, and compatible with background fields up to several hundreths of nanotesla. They also open the way to conformable helmets fitting all head morphologies with repositionable sensors, allowing for patient’s movements during the data recording.
These quantum sensors have been matured first for Space operation, in a large project with the European Space Agency. They demonstrated their robustness in Space from their launch in 2013 up to now. We adapted this technology to MEG and performed a first clinical trial in 2016, and strongly improved the performance of the sensors the following years. In 2017 we were awarded Best Early Stage Innovation among H2020 projects by a board of investors. In 2020 our startup project got the 2020 i-Lab French national innovation prize.
Our preliminary multi channels MEG device is currently used by several teams for clinical trials.
