Abstract

An odor compound release device includes a support that is deformed when an external stimulus is applied, and when the external stimulus is not applied, restored to its original state. A plurality of spaces are located in the support, have upper portions closed by the support, and are to be filled with odor compounds, wherein the upper portions are opened or closed by deformation or restoration of the support due to the application of the external stimulus. A member that is located in the support or on a surface of the support and applies the external stimulus to the support.

Claims

7. The odor compound release device of claim 6, wherein the support comprises at least one of a conductive polymer, a liquid crystalline elastomer, and a dielectric elastomer.

8. The odor compound release device of claim 6, wherein the member comprises an electrode configured to apply the voltage to the support.

9. The odor compound release device of claim 8, wherein the electrode is located on each of a first surface of the support and a second surface of the support which is opposite the second surface.

10. The odor compound release device of claim 1, wherein the support comprises a temperature sensitive phase transition polymer.

11. The odor compound release device of claim 10, wherein the support comprises poly(N-isopropylacrylamide) (PNIPAM).

12. The odor compound release device of claim 10, wherein the member comprises magnetic nanoparticles that are dispersed in the support and inductively heat the support when a magnetic field is applied.

13. The odor compound release device of claim 1, the member directly contacts the surface of the support.

14. An odor compound release device comprising:

a substrate having a plurality of outer surfaces and including a single layer of a plurality of internal spaces arranged in a plurality of arrays, each of the plurality of internal spaces configured to contain an odor compound;

a capping layer that is formed on an entire outer surface of the plurality of outer surfaces of the substrate and includes portions disposed at an inlet of the plurality of internal spaces that contact each other to close the inlet of the plurality of internal spaces, wherein the portions of the capping layer deform and separate to open the inlet of the plurality of internal spaces in response to an application of a stimulus, and are restored to contact each other when the stimulus is not applied; and

a member that is located in the substrate or on a surface of the substrate and is configured to apply the stimulus to the capping layer,

wherein inner surfaces of the substrate form the each of the plurality of internal spaces.

15. The odor compound release device of claim 14, wherein the capping layer comprises at least one of a natural rubber and a synthesized rubber.
