GMI
Giant Magneto Impedance magnetometer
This technology has been patent-filled on January 2020 under the number EP3848715 and is co-owned by University of Caen Normandy, National Graduate School of Engineering of Caen and National Center for Scientific Research.
Description:
GMI technology, for Giant MagnetoImpedance, provides a solution to the shortcomings of fluxgate sensors currently used in industry, notably by offering better sensitivity over a wide bandwidth.
The magnetometer is built using a dedicated electronic board. It consists of a sensing coil wound around a sensitive element
Advantages of the technology:
- Low noise
- Very high sensitivity, especially over a wide bandwidth (DC to 100 kHz)
- Long-term stability
- Low implementation cost and ease of use
Please find more about the technical features in the datasheet and the figure attached bellow.
Applications:
- Security: detection of vehicles or objects
- Mining and/or oil exploration; soil archaeology
- Underwater monitoring
- Non-destructive testing: analysis and inspection of ferromagnetic elements
- Healthcare: navigation surgery
- Defense: final guidance for anti-vehicle weapon systems
