Shielding Effects

The ultrahigh sensitivity atomic spin magnetometer as the magnetic measurement sensor has received much concern. The performance of the magnetic shielding cylinder is one of the key factors constraining the atomic spin magnetometer’s sensitivity. In order to effectively improve the performances of the magnetic shielding, the parameter optimization models of the magnetic shielding cylinder were established in this paper. Under the condition of changing only one parameter while the others keeping constant, the effects of various parameters influencing the axial shielding coefficient were comprehensively analyzed, and the results showed that the smaller the innermost length, the innermost radius, and the radial spacing were, and the greater the axial spacing was, the better the shielding performance could be obtained. According to these results and the actual needs, the magnetic shielding cylinder was optimally designed, and then the shielding effects were simulated via the software Ansoft. The simulation results showed that the optimized magnetic shielding cylinder had the advantages of small size, high shielding performance, and lager uniformity than that of the nonoptimized one. The actual measurement results showed that the residual magnetism in the optimized magnetic shielding cylinder was below 0.1 nT, which was 2~4 times lower than the nonoptimized one.

Ultrahigh Sensitivity

Nanofiber-based electronics with unique fibrous interlocked microstructures are capable of differentiating various mechanical stimuli, such as normal pressure, lateral strain, and bending. Skin-inspired electronics with an ultrahigh sensitivity of 71.07 kPa−1 under a small applied pressure (<0.06 kPa), a rapid response time (<2 ms), and highly reproducible stability (>5000 cycles) are reported, thereby demonstrating their potential applications in versatile human–machine interfaces.
