Problems solved by technology

[0007] The temperature sensing technology based on the difference in thermal expansion coefficient is ingeniously designed and novel, but the deformation caused by the difference in thermal expansion coefficient of heterogeneous composite materials is relatively weak, and there are also problems such as low temperature sensing resolution, low sensitivity, and small dynamic range. Mechanism defects, currently only in the stage of theoretical analysis and feasibility study

Abstract

The invention discloses a high-Q temperature-sensing Anapole resonant structure based on liquid metal, which is used in the technical fields of sensing detection, radiation control and the like. The invention is composed of n*n high-Q resonant units arranged periodically. This kind of high-Q resonant unit is designed according to the static ring dipole moment (Anapole) theory, combined with the thermal expansion, fluidity and other characteristics of liquid metal, so that the resonant unit has high-Q characteristics and can achieve higher temperature sensing resolution. At the same time, in order to improve the temperature sensing ability, a liquid storage structure is added to the resonant structure, so as to achieve higher sensing sensitivity.

Description

technical field [0001] The invention relates to the technical fields of sensory detection and radiation control, in particular to a high-Q temperature-sensing Anapole resonant structure based on liquid metal for temperature-sensing detection. Background technique [0002] Electromagnetic Metamaterials (Electromagnetic Metamaterials) is a class of artificially synthesized structural materials with singular electromagnetic properties. The design and preparation of new devices provide an effective way. There is a strong correlation between the resonant frequency / strength of electromagnetic metamaterials and unit structural parameters, dielectric material properties, and surrounding environmental factors. Based on this, new sensing technologies and implementation methods based on electromagnetic metamaterials can be developed, and can be widely used in sensing And detect the characteristics and changes of media, pressure, humidity, temperature, chemistry and biology in the envi...
