The method of operation of the pressure sensor comprising the first substrate structure SUB1, the second substrate structure SUB2, and the spacer 150, manufactured by the method described with reference to Figs. 1 to 4, Will be described with reference to Fig.

5 and 6 are views for explaining a method of operating a pressure sensor according to an embodiment of the present invention.

5 and 6, a pressure sensor according to an embodiment of the present invention includes, in addition to the above-described first substrate structure SUB1, the second substrate structure SUB2, and the spacer 150, 310 and a light-receiving unit 320. The light-

The light emitting unit 310 may irradiate the base light 312 with the first substrate structure SUB1 and / or the second substrate structure SUB2. The base light 312 may include light of various wavelength bands such as infrared rays, visible light, and ultraviolet rays. The light emitting unit 310 may include various light emitting elements such as an LED, an OLED, a fluorescent lamp, and a quantum dot.

The light emitting composite 110 of the first substrate structure SUB1 may excite the base light 312 emitted from the light emitting portion 310 to generate excitons. The excitons generated by the base light 312 may be re-emitted as a sensing light 322.

Alternatively, when external pressure is applied, the distance between the metal complex 210 and the light emitting composite 110 may be reduced, as shown in FIG.

Accordingly, it is possible to provide a pressure sensor capable of measuring the change in the amount of light by the pressure externally applied, and easily sensing whether the pressure is applied or not and the magnitude of the pressure.

In contrast to the above-described embodiment of the present invention, in the case of a pressure sensing element for sensing whether a pressure is applied and a pressure by using a piezoelectric material, There is a problem in that the reliability is deteriorated. In addition, in the case of a pressure sensing device that senses whether a pressure is applied or a pressure is measured by measuring a change in resistance or capacitance according to a pressure, there is a problem in that the sensing sensitivity is low. In addition, in the case of a pressure sensing element that senses the magnitude of the pressure applied and the pressure applied by measuring the resistance change by applying the graphene oxide to the polymer foam, the graphene is coated on the polymer foam and reduced High temperature treatment and chemical treatment are required, which complicates the process. In addition, in the case of the above-described pressure sensing elements, a process for manufacturing the electrode is essential because it senses whether the pressure is applied and the magnitude of the pressure through the amount of change in resistance or capacitance.

However, as described above, in the pressure sensor according to the embodiment of the present invention, the distance between the metal composite 210 and the light emitting composite body 110 can be adjusted by external pressure, The light amount of the sensing light 322 re-emitted by the light emitting composite 110 is measured according to the distance between the light emitting composite 210 and the light emitting composite 110, . As a result, a pressure sensor with a simplified manufacturing process and a simple structure and a reliable manufacturing method thereof can be provided.

The pressure sensor according to an embodiment of the present invention may further include a first substrate structure SUB1 having the light emitting composite body 110 and a second substrate structure SUB2 having the metal composite body 210 with the spacer 150 therebetween, And the substrate structure SUB2 may be stacked. As a result, the thickness of the pressure sensor can be made thinner than that of conventional pressure sensors. Accordingly, it is possible to provide a pressure sensor that is easy to adhere to a human body and is easy to apply to a wearable element, and a manufacturing method thereof.
