Ultra-Sensitive, Low-Power Magnetometer

The SSC Pacific team was able to develop a novel, magnetic sensor (The Advanced Dynamic Fluxgate Magnetometer ADFM), using newly-discovered aspects of the physics of coupled nonlinear oscillator networks that overcome many current limitations to deliver high-power efficiency and high sensitivity, at a lower cost and power than existing room temperature magnetometers. This new sensor is compact and lightweight with high resolution, can communicate with other sensors as part of a package. It detects slowly moving static and magnetic signals such as those produced by an intruder crossing a tripwire. Commercial/Market Potential This technology has the potential to be useful in security applications when placed around buildings or in areas to detect metal on intruders. It may be used as a very sensitive compass for direction-finding, or incorporated into a compact and deployable hand-held device. This system has many potential applications and great commercial promise. Finally, it can be used for security applications in littoral waters. Benefits Sensor can operate at a wider range of temperatures than existing sensors Reduced cost and power requirements Compact and Lightweight Easy operation Coupled core version can classify magnetic signals according to their frequency Configured to null out ambient static magnetic "clutter"
