Special Issue Information

Dear Colleagues,

Magnetic sensors are in high demand for a variety of technological applications, such as microelectronics, security electronic surveillance, automobile, aerospace and aircraft industries, energy harvesting and conversion, electrical engineering, informatics, magnetic recording, non-destructive testing in civil construction, medicine and biomedical engineering, etc.

Recent trends in magnetic sensors have required high sensitivity, a quick response, small size and stability. While reducing the production cost and power consumption, the industry has also seen the improvement of features and the finding of novel operating principles based on fundamental studies of novel materials and phenomena.

This Special Issue of Sensors aims to focus on the latest advances and novel ideas devoted to designing magnetic devices and applications, magnetic sensing technology, basic phenomena and fundamental studies of novel nanomaterials suitable for next-generation sensors. Short communications, research papers and review articles are welcome for consideration. Potential Special Issue topics include, but are not limited to, the following areas:

  • Fabrication techniques;
  • Magnetic characterization;
  • Fundamentals and physics involving basic effects, the theory and the modelling of magnetic sensors;
  • Nano- and micro technologies;
  • Nanosensors;
  • Magnetic materials, micro- and nanowires, thin films, ribbons and their advanced processing;
  • Magnetic sensor arrays and systems;
  • Novel and smart magnetic materials for sensor applications;
  • Smart composite materials with magnetic inclusions;
  • Magnetic sensors, such as Hall effect devices, magnetometers, magnetoimpedance sensors, magnetoresistance sensors, magnetoelastic sensors and flexible electronics;
  • Magnetic sensor development for applications in biomedicine, electronic surveillance, electrical engineering, informatics, magnetic recording, noncontact and non-destructive monitoring, automobile and aircraft industries, etc.

We look forward to receiving your valuable contributions to this Special Issue.

This paper presents the design, fabrication, calibration, and comprehensive characterization of a homemade tri-axial fluxgate magnetometer. The magnetometer, utilizing a ring core configuration, was developed to measure ultra-low magnetic fields with high sensitivity and stability. Critical stages from material selection to sensor geometry optimization are discussed in detail. A series of critical characterization processes were conducted, including zero-field voltage determination, scale factor calculation, resolution measurement, noise analysis, bias assessment, cross-field effect evaluation, temperature dependency, and bandwidth determination. The sensor demonstrated a minimum detectable magnetic field resolution of 2.2 nT with a noise level of 1.1 nT/√Hz at 1 Hz. Temperature dependency tests revealed minimal impact on sensor output with a maximum shift of 120 nT in the range of 60 °C, which was effectively compensated through calibration to less than 5 nT. Additionally, the paper introduces a model function in matrix form to relate the magnetometer’s output voltage to the measured magnetic field, incorporating temperature dependency and cross-field effects. This work highlights the importance of meticulous calibration and optimization in developing fluxgate magnetometers suitable for various applications, from space exploration to biomedical diagnostics.

To enhance the sensing performance of fiber-optic magnetic field sensors, we explored the design, optimization, and application prospects of a D-type fiber-optic magnetic field sensor. This D-type PCF-SPR sensor is metal coated on one side (the metal used in this study is gold), which serves as the active metal for SPR and enhances structural stability. Magnetic fluid is applied on the outer side of the gold film for SPR magnetic field sensing. Six internal air holes arranged in a hexagonal shape form a central light transmission channel that facilitates the connection between the two modes, which are the sensor’s core mode and SPP mode, respectively. The outer six large air holes and two small air holes are arranged in a circular pattern to form the cladding, which allows for better energy transmission and reduces energy loss in the fiber. In this paper, the finite element method is employed to analyze the transmission performance of the sensor, focusing on the transmission mode. Guidelines for optimizing the PCF-SPR sensor are derived from analyzing the fiber optic sensor’s dispersion curve, the impact of surface plasmon excitation mode, and the core mode energy on sensing performance. After analyzing and optimizing the transmission mode and structural parameters, the optimized sensor achieves a magnetic field sensitivity of 18,500 pm/mT and a resolution of 54 nT. This performance is several orders of magnitude higher than most other sensors in terms of sensitivity and resolution. The SPR-PCF magnetic field sensor offers highly sensitive and accurate magnetic field measurements and shows promising applications in medical and industrial fields. Full article
