PROBLEM TO BE SOLVED: To provide a novel microcapsule automatically vibrating in responce to a substrate, and application thereof.SOLUTION: A microcapsule comprises: a membrane; an aqueous solvent present in an inner region surrounded by the membrane; an enzyme present in the aqueous solvent; and a solid material present in the inner region. The membrane can expand and contract, transmits water and the substrate, limits to transmit a component forming the solid material, and raises a transmitting rate of the component with expansion. The enzyme causes a predetermined kind of environmental change in the microcapsule in responce to the substrate. Dissolubility of the solid material is improved in responce to the environmental change. |
