“…MR sensors are more suitable for position sensing because of the high sensitivity, low power consumption, and larger detection range in contrast with traditional Hall effect sensors. Sensor arrays are designed and constructed with GMR/TMR multilayer system to achieve two-dimensional and three-dimensional detections [156][157][158]. The close-packed MR sensor array was built to dynamically detect magnetic microparticles with high precision.…”

Magnetoresistance (MR) is the variation of a material’s resistivity under the presence of external magnetic fields. Reading heads in hard disk drives (HDDs) are the most common applications of MR sensors. Since the discovery of giant magnetoresistance (GMR) in the 1980s and the application of GMR reading heads in the 1990s, the MR sensors lead to the rapid developments of the HDDs’ storage capacity. Nowadays, MR sensors are employed in magnetic storage, position sensing, current sensing, non-destructive monitoring, and biomedical sensing systems. MR sensors are used to transfer the variation of the target magnetic fields to other signals such as resistance change. This review illustrates the progress of developing nanoconstructed MR materials/structures. Meanwhile, it offers an overview of current trends regarding the applications of MR sensors. In addition, the challenges in designing/developing MR sensors with enhanced performance and cost-efficiency are discussed in this review.

A type of Galfenol-piezoelectric composite film sensor is proposed in this paper, and its nonlinear magnetoelectric coupling dynamic characteristics are discussed. Nonlinear differential terms are introduced to explain the hysteresis of Galfenol's strain-magnetic-fieldintensity (MFI) curves, and a new Galfenol's model is established. The fitting effect of the Galfenol's model on the experimental data is proved by the partial least-squares regression method. A nonlinear dynamic model for such a sensor subjected to a harmonic magnetic field and a stochastic electromagnetic interference has been developed, and its strongly nonlinear dynamic response is obtained by the developed Lindstedt-Poincare (L-P) method. The results of numerical simulation show that the Galfenol-piezoelectric composite film sensor has complex dynamic characteristics; the stochastic electromagnetic interference plays an important role in the system's dynamic response. The results of this study are helpful for the optimal design and improvement of Galfenol-piezoelectric composite film sensors.

“…Magnetic field sensors have been applied as indispensable devices in many fields, such as biomedicine, aerospace and communication industries [1][2][3]. With the development of micro-electromechanical systems (MEMS) technology, the magnetic field sensor can be successfully integrated in micro size to achieve satisfactory performances, such as high sensitivity and low cost [4,5]. Recently, resonant magnetic field sensors have become a research hotspot due to their high resolution, and most of them exploit the magnetic fieldinduced Lorentz force to detect the parameters of magnetic field [6][7][8].…”

A novel magnetic field sensor is developed based on the microcantilever resonator to realize the parameter measurements of in-plane multi-axis magnetic field under different vibration modes. The working equations of the resonant sensor are established to calculate the strength and direction angle of measured magnetic field based on different resonances. The strength components of magnetic field along x-axis and y -axis are independently measured by the proposed resonant sensor under flexural and torsional resonant modes, respectively. The corresponding outputs of the sensor are linearly related to the magnetic field strength components. The finite element simulations are performed not only to prove the capability of the sensor to measure magnetic field under different modes, but also indicate the mode coupling of microcantilever resonator existed in the measurement. Thus, the coupling compensation method is proposed by amending ouput voltage of the sensor through experiments. The experimental results at atmospheric pressure show that the compensated accuracies of in-plane magnetic field are 3.06% (strength) and 1.59% (angle), and the measuring sensitivities are 98.79 µV mT−1 along x-axis and 92.46 µV mT−1 along y -axis, respectively.
