“…Findings from this study have also shown that the linear response of the device to an external applied magnetic field was 60µT at 3.478V and 70µT at 3.136V for the designed fluxgate sensor with MFB-BPF and SK-BPF respectively at 7.07Hz excitation frequency. This finding is quite different from that of [17] who obtained a linear sensor response of ±40µT at 100kHz excitation frequency while working on a flexible flat micro-fluxgate sensor with amorphous rectangular core, using a simple pad-printing technique. Based on the results obtained from the investigations of the two BPF's, the performance response of the MFB-BPF is better than that of the SK-BPF and hence, it adoption for the design and development of the high sensitive fluxgate sensor for earth magnetic field exploration.…”

Geomagnetic storms and sub-storms, sudden commencement, and geomagnetic pulsations are a worldwide disturbance of earth's magnetic field which causes significant damage across the world with a single event. Fluxgate sensor is essential in order to predict such occurrence of the major disturbances. In this study, comparative analysis of Multiple Feedback Band-Pass Filter (MFB-BPF) and Sallen Key Band-Pass Filter (SK-BPF) for the implementation of ferrite based high sensitive Fluxgate Sensor (FS) for earth's magnetic field explorations was carried out using Multisim MATLAB. The harmonics responses of the sensing coil output voltage for the designed fluxgate sensor was tested using the designed second-order MFB-BPF and SK-BPF. The prototype single-axis fluxgate sensor was used to obtain 2nd harmonic magnetic field response with Helmholtz coil. Results show that the 2nd harmonics produced the highest amplitudes of 45.61mV at an excitation current of 18.75mA for MFB-BPF and 51.20mV at excitation current of 50.00mA for the SK-BPF respectively. An indication that the core was strongly saturated at the 2nd harmonics and the MFB-BPF performance proved its superiority over the SK-BPF. The MFB-BPF can be adapted for the development of a high sensitive fluxgate sensor which can be used for earth magnetic field exploration.

In this article, a novel, non-contact method is proposed to detect cage slip of rolling bearing. The proposed method can obtain the speed signal of cage and inner raceway by the introduction of weak magnetic field detection technology simultaneously. Meanwhile, to enhance the identified accuracy of cage slip, an adaptive filtering method is developed to suppress noise in weak magnetic field sensor output signal. The method adopts complementary complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) to decompose the weak magnetic field sensor output signal into a set of intrinsic mode functions adaptively. The intrinsic mode functions contain noisy component of detection signal (noisy intrinsic mode functions) as well as corresponding signal component of the roller and inner raceway (signal intrinsic mode functions). The noisy- and signal intrinsic mode functions are identified by the development of reconstruction criterion. The criterion is determined based on upper boundary of rotational frequency of roller under pure rolling conditions. Then, the noisy intrinsic mode functions are forced to zero, and signal intrinsic mode functions are reconstructed to extract the speed information of roller and inner raceway. An experiment system is developed to verify the effectiveness of proposed method. The experiment result shows that the cage slip decreases with the increment in load under the given speed conditions and increases with the increment in speed under the given load conditions, as well as the cage slip is more serious under given no-load conditions. It shows that the weak magnetic field detection technology can be used to detect the cage slip of rolling bearing.

“…Schoinas et al reported a flexible, flat, miniaturized fluxgate sensor that was fabricated by the pad/printing technique. , As shown in Figure A(a) and A(b), silver-based inks were used as the conductive tracks, the resin was used for the insulation layer, and a 25 nm thick ribbon from Vitrovac 6025Z (VACUUMSCHMELZE GmbH & Co. KG) was selected for the soft magnetic core and fixed to the insulation layer by an epoxy-based glue. The dimensions of the entire fluxgate sensor were 40 mm × 20 mm × 0.3 mm, fabricated on a 127 μm Kapton substrate.…”

Flexible magnetic field nanosensors hold immense potential for wearable electronics, offering a range of advantages such as comfort, real-time health monitoring, motion sensing, durability, and seamless integration with other sensors. They are expected to revolutionize wearable technologies and drive innovation in various domains, enhancing the overall user experience. In this review, we provide an overview of recent advances in flexible magnetic field nanosensors, including flexible Hall sensors, flexible magnetoresistive (MR) sensors such as giant magnetoresistance (GMR), magnetic tunnel junction (MTJ), and anisotropic magnetoresistance (AMR) sensors, flexible fluxgate sensors, and flexible giant magnetoimpedance (GMI) sensors. We discuss different fabrication methods and real-life applications for each type of sensor as well as the technical challenges faced by these sensors. The use of these flexible nanosensors opens more possibilities for human−computer interaction and presents exciting opportunities for wearable technology in diverse fields. The robustness of these sensors along with the trend to reduce energy consumption will continue to be important research areas. Future trends in flexible magnetic field nanosensors include energy harvesting from the body, miniaturization and lower power consumption, improved durability and reliability, and reduced cost. These advancements have the potential to drive the widespread adoption of flexible magnetic field nanosensors in wearable devices, enabling innovative applications and enhancing the overall user experience.
