Cerca Magnetics Limited

Cerca Magnetics Limited offer the worlds most advanced functional brain scanner an integrated lightweight, ergonomic and wearable device that will offer an unparalleled window on human brain function, in health and disease. We have developed and brought to market the worlds first commercial, fully integrated brain imaging device based on optically-pumped magnetometers (OPMs), the Cerca OPM-MEG System. Conventional magnetoencephalography (MEG) systems employ cryogenic sensors cooled to -269 C using liquid Helium to measure the extremely small fields generated by the brain. However, the need for cryogenic infrastructure severely limits usability and system performance. New breakthroughs in physics have enabled fabrication of devices that exploit the quantum properties of atoms to measure very small magnetic fields. These sensors, known as optically-pumped magnetometers (OPMs) do not need liquid helium cooling, and they are around the size of a Lego brick. This means they can be...
