DARPA AMBIIENT developing ultrasensitive Magnetometers

State-of-the-art magnetometers are used for diverse civilian and DoD applications, among them biomedical imaging, navigation, and detecting unexploded ordnance and underwater and underground anomalies.   Each beat of your heart or burst of brain activity relies on tiny electrophysiological currents that generate minuscule ripples in the surrounding magnetic field. These field variations provide the basis…
