In this article, an innovative approach for magnetic data communication is presented. For this purpose, the receiver coil of a conventional magneto-inductive communication system is replaced by a high-sensitivity wideband magnetic field sensor. The results show decisive advantages offered by sensitive magnetic field sensors, including a higher communication range for small receiver units. This approach supports numerous mobile applications where receiver size is limited, possibly in conjunction with multiple detectors. Numerical results are supported by a prototype implementation employing an anisotropic magneto-resistive sensor.

A novel micro-structured fiber magnetic field sensor based on magnetic fluid (MF) filling is proposed. The air hole radius in the cladding of fiber is reduced from inner layer to outer layer, and the numerical analysis is performed by the finite element method (FEM). For the [Formula: see text]-pol mode, the proposed sensor has an average sensitivity of 960.61 pm/Oe, and for the [Formula: see text]-pol mode, the average sensitivity can reach 884.85 pm/Oe. The sensor has the advantages of small size and high sensitivity and is competitive in magnetic field sensors.

Abstract The article proposes a method for organizing the communication interface of an unmanned vessel and its operator. The interface contains manual controls for the course and speed of the vessel by regulating the angle of the rudder blade shift and the speed of rotation of the propeller shaft, an automatic system for keeping the vessel on a given trajectory for the purpose of navigating the vessel in automatic and manual modes. The interface comprises a system for obtaining filtration, storing the required kinematic and navigation data for identifying mathematical models of the vessel’s movement and the functioning of the autopilot. The interface allows adjusting the PID controller for automatic guidance of the vessel along the trajectory in real time to optimize automatic control, to correct the readings of the GPS and the Earth’s magnetic field sensors, to calibrate the Earth’s magnetic field sensor. The interface includes graphic and digital fields for displaying kinematic and navigation data on the vessel, autopilot and information on the operation of the operator-vessel complex. The interface allows the exchange of data between the operator and the vessel by means of a data transfer protocol via TCP-IP stack protocols on the radio frequencies of public Wi-Fi networks. The interface is created by means of appdesigner tools on the MATLAB platform.

Superconducting Quantum Interference

One of the new materials that have recently attracted wide attention of researchers are magnetoelectric (ME) composites. Great interest in these materials is due to their properties associated with the transformation of electric polarization/magnetization under the influence of external magnetic/electric fields and the possibility of their use to create new devices. In the proposed review, ME magnetic field sensors based on the widely used structures Terfenol—PZT/PMN-PT, Metglas—PZT/PMN-PT, and Metglas—Lithium niobate, among others, are considered as the first applications of the ME effect in technology. Estimates of the parameters of ME sensors are given, and comparative characteristics of magnetic field sensors are presented. Taking into account the high sensitivity of ME magnetic field sensors, comparable to superconducting quantum interference devices (SQUIDs), we discuss the areas of their application.

Abstract A terahertz band temperature and magnetic field sensor based on a magneto-fluid-filled D-type microstructure grating is designed. The high sensitivity measurement of temperature and magnetic field is realized by optimizing the structure. The highest temperature sensitivity is 233.88 pm/°C, and the highest magnetic field sensitivity is up to 214.802 pm/mT. When the overall structure size of the sensor was changed by ±0.1 %, the maximal absolute deviation of temperature or magnetic field sensor are 0.018 pm/℃ and 0.03 pm/Oe. At the same time, the dual-parameter demodulation matrix is used to effectively overcome the crosstalk problem.

A surface-acoustic-wave (SAW) magnetic-field sensor utilizing fundamental, first- and second-order Love-wave modes is investigated. A 4.5   μ m SiO2 guiding layer on an ST-cut quartz substrate is coated with a 200 n m (Fe90Co10)78Si12B10 magnetostrictive layer in a delay-line configuration. Love-waves are excited and detected by two interdigital transducers (IDT). The delta-E effect in the magnetostrictive layer causes a phase change with applied magnetic field. A sensitivity of 1250 ° / m T is measured for the fundamental Love mode at 263 M Hz . For the first-order Love mode a value of 45 ° / m T is obtained at 352 M Hz . This result is compared to finite-element-method (FEM) simulations using one-dimensional (1D) and two-and-a-half-dimensional (2.5 D) models. The FEM simulations confirm the large drop in sensitivity as the first-order mode is close to cut-off. For multi-mode operation, we identify as a suitable geometry a guiding layer to wavelength ratio of h GL / λ ≈ 1.5 for an IDT pitch of p = 12   μ m . For this layer configuration, the first three modes are sufficiently far away from cut-off and show good sensitivity.
