Recently, many people have challenged wearable devices. Wearable devices need to be able to constantly exchange information with users through sensors. Sensors used for the purpose of detecting various conditions output information in many cases as electrical signals. Signals transmitted as electrical signals have many advantages, but the need for low power, flexible sensors for long time use is increasing. The plasmonic noble metal is also used in color change papers using nanoparticles. These particles form a chain structure, form a plasmon coupling, and have a plasmon resonance on the surface. The reflectance of the surface changes by physical force, which is used for color sensors. In the papers describing the color change using nanoparticles, most use plasmonic noble metal as a particle. Plasmonic noble metal particles form a plasmon coupling forming a chain structure and has plasmon resonance on the surface. The reflectance of the surface is changed by physical force, and this characteristic is used in color sensors. For example, Au noble metal colloidal nanoparticles can be seen using plasmon resonance characteristics to show a change in color. In addition, Plasmonic microgel is magnified with temperature and color changes, so it is observed that the saturation changes with the temperature appear. Ag@Fe3O4 a film sensor using nanoparticles can visually represent a physical change and apply it to various movements. In addition, the advantage of being able to change the color of the sensor depending on the size of the nanoparticles will be used in a wide range during the actual application. In this paper, only physical reactions will show that the color changes without current and explain the principle. This will be able to achieve the purpose as a sensor by showing a definite change that differs from the saturation or brightness. To solve this problem, this paper attempts to fabricate a low-power, flexible physical sensor using photonic crystals and to verify the results of various experiments.
