This work reports a highly sensitive resonant Faraday force magnetometer with a minimum detectable rms magnetic field of 277 fT at 17.2 Hz suitable for magnetoencephalography and brain circuit imaging at room temperature. At this level of sensitivity, our sensor can favorably compete with superconducting quantum interference devices (SQUIDs) without requiring liquid helium cooling and with the possibility of monitoring brain activity in humans behaving in our natural environment.
