Reflective Highly Sensitive Fabry–Perot Magnetic Field Sensor Based on Magneto-Volume Effect of Magnetic Fluid

IEEE Transactions on Instrumentation and Measurement, 2021
A magnetic field measurement method based on the magneto-volume effect of magnetic fluid (MF) and Fabry–Perot (FP) interferometer (FPI) is proposed, which has higher magnetic field sensitivity and shorter response time than the traditional optical fiber ...

An All-Optical Vector Magnetic Field Sensor Based on Magnetic Fluid and Side-Polished Hollow-Core Optical Fiber

IEEE Sensors Journal, 2021
We demonstrate an optical fiber vector magnetic field sensor based on Mach-Zehnder interferometer by splicing a section of side-polished hollow-core fiber between two sections of single-mode fiber.

Graphene Magnetic Field Sensors

IEEE Transactions on Magnetics, 2010
Graphene extraordinary magnetoresistance (EMR) devices have been fabricated and characterized in varying magnetic fields at room temperature. The atomic thickness, high carrier mobility and high current carrying capabilities of graphene are ideally suited for the detection of nanoscale sized magnetic domains.

Integrated magnetic field sensor

Sensors and Actuators A: Physical, 1991
Abstract For small magnetic field measurements, Sextant Avionique is developing, in collaboration with the Ecole Superieure d'Ingenieurs en Electrotechnique et Electronique, a new generation of miniature sensors. The detector is a mechanical resonator using a monocrystalline silicon beam.

Magnetic field sensor based on ring WGM resonator infiltrated with magnetic fluid

, 2020
A highly-sensitive magnetic field sensor based on magnetic fluid (MF) infiltrated ring whispering gallery mode (WGM) resonator was proposed and demonstrated in experiment. The resonator was fabricated by attaching a corrosive hollow-core fiber (HCF) to a

Monolithic piezoresistive CMOS magnetic field sensors

Sensors and Actuators A: Physical, 2003
Abstract Two original electromechanical magnetic sensors have been developed using a fully industrial fabrication process that relies on bulk wet etching of CMOS dies. The first device uses the Lorentz force to actuate a U-shaped cantilever beam, while piezoresistive polysilicon gauges convert the beam bending into an electrical signal. A 2 μT sensor
