This invention provides a temperature-self-calibrated current sampling device and method. The device includes a constant current source, a sensing unit, an analog-to-digital converter, a measurement unit, and a computing unit. The sensing unit is divided into a reference resistor region and a sampling resistor region, which are electrically isolated and thermally coupled. By ensuring consistency in material systems, packaging forms, and deployment environments between the reference resistor region and the sampling resistor region, they exhibit essentially synchronized temperature change characteristics during operation. This enables real-time and accurate compensation for resistance drift in the sampling resistor based on the reference resistor, avoiding compensation deviations caused by thermal conduction delays or temperature detection lags in traditional temperature compensation schemes.

This invention relates to the technical field of materials science, and in particular to a multiphase material with a gradient interface phase and its preparation method, comprising a first phase material, a second phase material, and a gradient functional layer located at the interface between the two. The concentration of at least one substance in the gradient functional layer varies continuously or quasi-continuously from the region near the first phase to the region near the second phase. During preparation, a pre-formed layer containing a second-phase precursor and functional filler is first constructed on the surface of the first phase, and then combined with the second phase for molding. Physicochemical reactions allow the substances to penetrate and fuse across the interface, forming a gradient structure in situ. This application can eliminate performance abrupt changes at heterogeneous interfaces, effectively alleviate stress concentration, and suppress delamination failure. Through this design, the interfacial bonding strength and overall mechanical properties of the material are significantly improved, with bending strength increasing by up to 15.4%. It is applicable to various material systems and has strong prospects for industrial application.

The application belongs to but is not limited to the technical field of condensed matter physics and quantum functional devices, and discloses a two-dimensional topological superconducting device with negative magnetoresistance and spin Hall effect. The device is based on a single-layer In2O two-dimensional material to construct a device system. By utilizing the II-type Dirac point structure formed near the Fermi level of the material, and splitting into Weyl points with non-zero topological charge under the spin-orbit coupling effect, a nontrivial topological electronic structure is formed in the momentum space. The two-dimensional topological superconducting device proposed in the application theoretically realizes the unification of topological state, negative magnetoresistance, spin Hall effect and superconducting behavior in the same material system, avoids the shortcomings of relying on complex heterostructures or multi-material systems in the prior art, and has the advantages of simple structure, easy integration and synergistic regulation of multiple physical effects.

We provide an improved multi-functional material system. [Solution] The multifunctional material system has a first side and a second side opposite to the first side. The multifunctional material system comprises a variable permeability layer configured to be applied to a first surface of a substrate, and a desiccant layer applied to the surface of the variable permeability layer, which is adjacent to the substrate and opposite to other surfaces of the variable permeability layer. On both the first and second sides of the multifunctional material system, when humidity is high, water or water vapor flows into the desiccant layer through the variable permeability layer. On both the first and second sides of the multifunctional material system, when humidity is low, water or water vapor flows out of the desiccant layer through the variable permeability layer. The rate of inflow of water or water vapor into the desiccant layer through the variable permeability layer when humidity is high is greater than the rate of outflow of water or water vapor from the desiccant layer through the variable permeability layer when humidity is low.
