Abstract

The invention discloses a flexible photon pressure sensor, a preparation method and application thereof. The preparation method comprises the following steps: preparing a photonic crystal precursor solution; preparing a flexible substrate precursor solution, wherein the flexible substrate precursor solution contains sodium alginate; and compounding the photonic crystal precursor solution and the flexible matrix precursor solution to obtain the flexible photon pressure sensor. The sensor can generate corresponding optical signal changes for the deformation of the flexible substrate; and the response is real-time, is not influenced by propagation distance, electromagnetic interference or noise, and has better mechanical property and higher sensitivity.

Description

technical field [0001] The invention relates to the technical field of sensing materials, in particular to a flexible photonic pressure sensor, a preparation method and an application thereof. Background technique [0002] Flexible sensors with high sensitivity and multifunctional integrated response are of great significance for applications such as general health, artificial intelligence, and human-machine dialogue. As the marine environment continues to deepen, it has been noticed that sound waves are also a type of pressure wave. For the detection of the marine environment, hydrophones are usually used. The sensitivity of sensors in traditional hydrophones is limited, and it is impossible to truly feed back the ocean environment. [0003] Structural color based on the width of the photonic crystal bandgap causes reflection of light at a given wavelength. The reflection wavelength is determined by the structural parameters of the photonic crystal. Any change in the st...
