Abstract
Depending on applications, there were some problems that the sensor output will be easily saturated with geomagnetism owning to its high sensitivity. Therefore we present the design of MI sensor which is not saturated with geomagnetism, while retaining low noise density of 10 pT/Hz0.5 at 10 Hz . Then we verify that the particle with a size of 0.3 mm would be enough detected. In our presentation, we also introduce a demo unit for foreign body detection.
