Abstract

The invention belongs to the technical field of pressure sensing, and particularly relates to a pressure sensing device based on circular dichroism; the device comprises a metal film with a gap, a flexible material I, a metal block, a flexible material II, metal particles, a flexible material with holes and a rectangular cavity; the flexible material I is arranged on the metal film with the gap. Indirect coupling is achieved through the two staggered metal blocks and the continuous metal film, a U-shaped current is formed, the difference between the left-hand circularly polarized light irradiation and the right-hand circularly polarized light irradiation is large, large circular dichroism is obtained, and after metal particles enter the cavity, under the irradiation of the circularly polarized light, the metal film with the gaps is equivalently filled with metal particles, and the metal film with the gaps is equivalently connected with the lower layer. An electric current may flow through the metal particles. The larger the pressure is, the more the metal particles in the cavity are, the larger the current is, and the two semicircular metal blocks on the upper layer achieve indirect coupling.

Description

technical field [0001] The invention relates to the technical field of pressure sensing, in particular to a pressure sensing device based on circular dichroism. Background technique [0002] Accurate, reliable pressure measurement is important to many industries, not only fluidization processes. And involving health care, agriculture, transportation and other fields, in scientific fluid mechanics, engineering, accurate pressure sensors are also key to basic scientific research. [0003] When measuring the pressure sensing device in the prior art, the measured data results are not accurate enough, which affects the experimental results of basic scientific research. Therefore, the prior art needs to be improved. Contents of the invention [0004] The object of the present invention is to provide a pressure sensing device based on circular dichroism, which solves the problem that the measured data results of the pressure sensing device are not accurate enough during measurem...
