Fueling applications as diverse as medical diagnostics and self-driving cars, magnetometers are a critical factor in todayâs world, The most sensitive magnetometers, however, can only operate at extreme temperatures and in a shielded environment that isolates the sensor from ambient magnetic fields. Sonera Magnetics is developing a magnetometer that can operate at room temperature and in portable form factors with sensitivity comparable to the best magnetic sensors available today, dramatically increasing potential applications. These novel magnetometers enable low-cost, portable medical diagnostic tools. An example: evluationof brain activity is critical to the diagnosis and treatment of a variety of neurological disorders including epilepsy, traumatic brain injury, and Alzheimerâs disease. The most powerful non-invasive imaging technique for brain activity, magnetoencephalograpy, uses machines the size of an MRI, require liquid helium and magnetic shielding to operate, are costly botht to buy and to operate. Removing the need for magnetic shielding and cryogenic equipment, Sonera's systems enable a small, portable MEG system both at a lower cost per unit and in terms of oreating co
