“…In addition, in all four cases, we can observe the fact that the value of clamping itself is higher than the values given by the manufacturer. The opening values, which are a more important indicator than the closing ones, are in some cases even twice as high as the values given by the manufacturer [ 27 ].…”

Magnetic contacts we could define as a switching device used in transport structures such as a tunnel, to which the manufacturer prescribes a certain number of closures within its lifetime, during which they should operate flawlessly. Verification of the data provided by the manufacturer is time-consuming and physically demanding due to the data being large in number. For this reason, we developed a test device using torque in the research of magnetic contacts, which greatly automates the whole process and thus eliminates human error. The test device can use internal memory to calculate the number of closures of magnetic contacts and then transmit the digitized data. The test device is registered as an industrial utility model and can be used to test any magnetic contacts.

“…Magnetic anomaly detection (MAD) technology is an excellent passive positioning technology. Due to its all-weather, low-cost, and concealment, it is widely used in military and civilian fields such as unexploded ordnance (UXO) detection [3][4][5], underwater target detection [6,7], mineral exploration [8], industrial nondestructive testing, and biomedicine [9]. Over several years of development, MAD technology has gone through three stages [10]: total magnetic intensity (TMI) detection, magnetic field vector and gradient detection, and magnetic gradient tensor (MGT) detection.…”

Magnetic anomaly detection (MAD) technology based on the magnetic gradient tensor (MGT) has broad application prospects in fields such as unexploded ordnance detection and mineral exploration. The difference approximation method currently employed in the MGT measurement system introduces measurement errors. Designing reasonable geometric structures and configuring optimal structural parameters can effectively reduce measurement errors. Based on research into differential MGT measurement, this paper proposes three simplified planar MGT measurement structures and provides the differential measurement matrix. The factors that affect the design of the baseline distance of the MGT measurement system are also theoretically analyzed. Then, using the magnetic dipole model, the error analysis of the MGT measurement structures is carried out. The results demonstrate that the planar cross-shaped structure is optimal, with the smallest measurement error, only 3.15 × 10−10 T/m. Furthermore, employing the control variable method, the impact of sensor resolution constraints, noise level, target magnetic moment, and detection distance on the design of the optimal baseline distance of the MGT measurement system is simulated and verified. The results indicate that the smaller the target magnetic moment, the farther the detection distance, the lower the magnetometer resolution, the greater the noise, and the greater the baseline distance required. These conclusions provide reference and guidance for the construction of the MGT measurement system based on triaxial magnetometers.

The use of functional polymer materials to obtain high-performance biosensors is currently a research hotspot in the field of analysis and materials. Polymer materials have the advantages of good biocompatibility, easy design and controllable preparation of reactive groups, and rich functional types, which are helpful to construct biosensor interfaces with excellent performance. This work aims to study the application of functional polymer materials in environmental biosensors in the context of the Internet of Things, prepare silver nanocubes on Nafion membranes with ATP as a buffer, and establish a new optical detection method. Formaldehyde based color change of the film. In addition, a new method for detecting temperature and spermine using the conformational changes of polythiophene (PT) derivatives under certain conditions was established. According to the color and fluorescence changes of PT induced by iodide ions in the range of 25.5℃-50.5℃, a rapid and sensitive method for temperature detection was established. The establishment of this method shows that polythiophene derivatives can be used as a new type of temperature sensor, thus expanding the application range of PT. In addition, to further validate the method, real beef and chrysanthemum samples were tested, and the detection recoveries ranged from 85.6% to 103%, indicating that the method is feasible for spermine detection.
