Special Issue Information

Dear Colleagues,

Magnetic field detection has become increasingly important in scientific research, industrial production, and daily life. In recent years, with the development of new magnetosensitive materials, magnetic sensing mechanisms, and novel sensor technologies, the performance of magnetic sensors has improved significantly. This Special Issue aims to present the latest research advancements in high-performance magnetic sensors. Topics include spin-valve magnetic sensors based on novel magnetoresistive thin-film materials and structures, magnetostrictive-effect magnetic sensors based on new materials, magnetoimpedance magnetic sensors based on new ferromagnetic materials and structures, and novel magnetic sensors based on flexible materials and MEMS technology. Additionally, this issue will present current research on magnetic sensing technologies involving spintronics effects, magnetoelectric effects, magneto-optical effects, quantum mechanics effects, high-temperature superconductivity effects, and optical pumping effects. Furthermore, the latest applications of magnetic sensing technology in industrial automation, consumer electronics, medical health, aerospace, smart grids, and security fields will be showcased. This issue aims to present the current state and trends in magnetic sensing technology from the perspectives of materials, mechanisms, and applications.

Smart clothes equipped with flexible sensing systems provide a comfortable means to track health status in real time. Although these sensors are flexible and small, the core signal-processing units still rely on a conventional printed circuit board (PCB), making current health-monitoring devices bulky and inconvenient to wear. In this study, a printed fabric-based hybrid circuit was designed and prepared—with a series of characteristics, such as surface/sectional morphology, electrical properties, and stability—to study its reliability. Furthermore, to verify the function of the fabric-based circuit, simulations and measurements of the circuit, as well as the collection and processing of a normal adult’s electrophysiological signals, were conducted. Under 10,000 stretching and bending cycles with a certain elongation and bending angle, the resistance remained 0.27 Ω/cm and 0.64 Ω/cm, respectively, demonstrating excellent conductivity and reliability. Additionally, the results of the simulation and experiment showed that the circuit can successfully amplify weak electrocardiogram (ECG) signals with a magnification of 1600 times with environmental filtering and 50 Hz of industrial frequency interference. This technology can monitor human electrophysiological signals, such as ECGs, electromyograms (EMGs), and joint motion, providing valuable practical guidance for the unobtrusive monitoring of smart clothes.
