MAG4Health

MAG4Health operates in neurotechnology and brain imaging, focusing on wearable magnetoencephalography rather than general-purpose medical devices. Its described differentiation is the use of helium-4 optically pumped magnetometers that work at room temperature, avoiding the need for sensor heating or cooling. The flexible helmet is specified to support 16 to 96 sensors and accommodate different head shapes, with sensors placed directly on the scalp. Other stated technical features include three-axis closed-loop measurement, a dynamic range of up to 200 nT, real-time sensor localization, and data export in FIFF format. The system is also described as working with standard magnetic shielding without additional field-nulling coils. The company’s research-system positioning and the stated absence of medical or regulatory approvals distinguish its current described offering from products represented as approved for clinical use.

Its described research system combines room-temperature helium-4 optically pumped magnetometers with a flexible 16-to-96-sensor helmet, three-axis closed-loop measurement, and automatic three-dimensional sensor localization. Those capabilities indicate an effort to address practical MEG constraints, including sensor placement and accommodation of different head shapes. The system is presented for research, with possible relevance to the development of clinical applications; the available product description says it does not yet have medical or regulatory approvals. A hiring note says there were no open positions in October 2022, but it is too old to indicate current hiring direction.
