ABSTRACT:
The present invention provides a self-metabolic functional material comprising a functional ferromagnetic particles dispersed in a fluid, each of the particles comprising a functional component and a chemically reactive ferromagnetic component with a characteristic of losing a ferromagnetism thereof by a chemical reaction proceeding with time, the functional ferromagnetic particles losing the ferromagnetism by the chemical reaction of the ferromagnetic component with time. The self-metabolic functional material has a desired function and gradually loses its function by being used. The degradation or loss of the function of the material can be detected by degradation or loss of ferromagnetism. By using such a material in the self-metabolic functional apparatus comprising a carrying device and a supply device, the self-metabolic functional material is self-metabolized as follows: The function of the self-metabolic functional material is degraded or lost, and at the same time the ferromagnetism is degraded or lost; and then the self-metabolic functional particles can not be carried on the carrying means. Fresh self-metabolic functional material comprising self-metabolic functional particles by either ferromagnetism and functionality, is carried on the carrying device by the supply device.
