Investigation of vehicle induced magnetic anomaly by triple-axis magnetoelectric sensors

This paper investigates magnetoelectric (ME) sensors for vehicle detection. We propose a novel triple-axis ME magnetic sensor system consisting of tri-layers of Metglas/ Pb(Zr, Ti)O-3/Metglas laminates together with its fabrication and installation methods. This non-intrusive ME sensor system with a larger sensing range is viable for detection and recognition of vehicle induced magnetic signatures in an outdoor (open) environment. We also show a finite element simulation method capable predicting the magnetic anomaly projection in the geomagnetic field.
