Flexible magnetic field sensor technologies
Spintronics XIV, 2021Conventional magnetic field sensors are fabricated on flat substrates and are rigid. Extending 2D structures into 3D space relying on the flexible electronics approaches allows to enrich conventional or to launch novel functionalities of spintronic-based devices.

IEEE Journal of Solid-State Circuits, 1983
The authors present a novel, fully integrated magnetic field sensor made in the standard, polysilicon-gate CMOS technology. The circuit shows a sensitivity of 1.2 V/T with 10 V supply voltage and 100 /spl mu/A current consumption. The circuit consists of a pair of split-drain MOS transistors in a CMOS-differential amplifier-like configuration.

Advances in Magnetic Field Sensors
IEEE Sensors Journal, 2010The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally found applications. We also review the development of miniaturization of fluxgate sensors and refer briefly to SQUIDs, resonant ...

Microstrip sensor of magnetic fields
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004Using a quasi-static approximation, the construction of a weak magnetic field sensor containing a thin magnetic film is researched and optimised. A sensitivity comparison of the sensor with a polycrystalline Permalloy film and the sensor with a monocrystalline yttrium-iron garnet film is carried out.
