Paper by ECE-NTUA Circuits & Systems Group Students in the Anniversary Special Issue on 20 Years of IEEE SENSORS Journal
We are pleased to announce that the paper "Vector Magnetic Field Sensors: Operating Principles, Calibration, and Applications” was included in the Special Issue published to celebrate the 20th anniversary of the prestigious IEEE Sensors Journal.
The paper was co-authored by Neoclis Hadjigeorgiou (Ph.D. candidate, ECE NTUA), Konstantinos Asimakopoulos (Ph.D. candidate, ECE NTUA), Konstantinos Papafotis (Ph.D. candidate, ECE NTUA) and Paul P. Sotiriadis (Professor, ECE NTUA).
ABSTRACT: This review paper explores the most common technologies of vector magnetic field sensors. Specifically, the AMR, GMR, TMR, GMI, Hall, Fluxgate, Search Coil and SQUID sensors are considered. The physical phenomena that permit their operation as well as the structure and operating principles of each sensor are presented. In addition, the basic linear, time-invariant error sources of magnetic sensors are described along with some popular calibration techniques. Finally, some representative application examples of each sensor are described.
