Magnetic liquid sensor in orthogonal magnetic fields
Sensors and Actuators A: Physical, 1997Abstract In this paper we present a sensor set-up based on magnetic liquids and provided for devices designed to measurement and control of physical parameters as: slope, displacement, acceleration, vibration parameters, value and direction of a magnetic field, etc. The sensor is under the influence of two crossed magnetic fields; one is a continuous

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.

Photonic Magnetic Field Sensor
2002Abstract : Small, in-line polarization rotators or isolators to reduce feedback in fiber optic links can be the basis for excellent magnetic field sensors. Based on the giant magneto-optical (GMO) or Faraday effect in iron garnets, they with a magnetic field of a few hundred Gauss, (20 mT) for an interaction length for an optical beam of a few ...

Three-dimensional magnetic-field sensors
IEEE Transactions on Electron Devices, 1988Devices sensitive to all three components of a magnetic-field vector are presented. The sensitivity to two field components in the plane of the chip is achieved by merging two one-dimensional vertical magnetotransistors positioned at a 90 degrees angle to each other.
