Abstract

The invention discloses an electromagnetism-like induced transparent high-Q-value temperature sensing resonance structure based on liquid metal. The electromagnetism-like induced transparent high-Q-value temperature sensing resonance structure is applied to the temperature sensing detection field, and in order to solve the problem that an existing sensor is low in sensitivity, the electromagnetism-like induced transparent high-Q-value temperature sensing resonance structure is designed according to the electromagnetism-like induced transparency theory in combination with the characteristics ofthermal expansibility, fluidity and the like of liquid metal, so that the resonance unit has the characteristic of high Q value, and the higher temperature sensing resolution can be achieved. And meanwhile, in order to improve the temperature sensing capability, a liquid storage structure is added in the structure, and the wire diameter of the liquid metal resonance structure is reduced, so thatthe higher temperature sensing sensitivity is realized.
