WEARABLE DEVICE MADE BY AMORPHOUS ALLOY WITH ANTIBACTERIAL FUNCTION

Abstract

A wearable device made by amorphous alloy with antibacterial function includes a functional part adapted for implementing using functions of the wearable device; and an amorphous alloy housing configured out of the functional part and adapted for cladding the functional part to prevent the functional part from directly contacting with a user. Since the wearable device has the amorphous alloy housing covering on the functional part, thus the amorphous alloy housing rather than the functional part will contact with the user skin directly. As the amorphous alloy has excellent bactericidal capability, thus user wearing such a wearable device will get a good user experience.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

[0022] The present invention is directed to a wearable device that is made by amorphous alloy with antibacterial function, so as to improve use experience and meet the user demand. The wearable device can be a sport watch, a sport bracelet, a heart rate testing band, or a health monitoring bracelet, etc.

[0023] The amorphous alloy with antibacterial function has the following compositions: Ag 2 wt %8 wt %; Eu 1 wt %3 wt %; Ce 1 wt %3 wt %; Mg 20 wt %40 wt %; Cu 40 wt %60 wt %; Zn 3 wt %10 wt %; and Al 1 wt %5 wt %. Such an amorphous alloy made by these metals is antibacterial and bactericidal. Antibacterial function means that, at proliferation stage of bacteria, these metals are absorbed on the cytoderm and combined with the cytomembrane, thus the enzyme in the cytomembrane will be destroyed to prevent electron transport of energy metabolism required by cell growth, thereby inhibiting bacterial individual growth. Bactericidal function means that, at non-proliferation stage of bacteria, these metals destroys the enzyme in the cytomembrane to kill the bacteria due to normal energy metabolism required by cell growth is inhibited.

[0024] Therein, Ag has the strongest bactericidal capability, while Ce and Eu are active metals in the rare-earth elements, which are served as alloy additive to improve the bactericidal capability of the alloy. That's because Ag, Ce and Eu show synergistic antibacterial activity, and can contact with cytomembrane by electric field adsorption to destroy sheath structure and wall structure of the bacterial, thereby improving bactericidal effect of the amorphous alloy regarding to staphylococcus aureus and escherichia coli, and achieving sterilization rate up to 99.99 wt %. Furthermore, the alloy has excellent photo stability.

[0025] For example, as shown in FIG. 1 of a sport watch that is made of amorphous alloy with antibacterial function, the sport watch includes a functional part 100 and an amorphous alloy housing 200 configured out of the functional part 100 and adapted for cladding the functional part 100. Specifically, the functional part 100 is adapted for implementing using functions of the wearable device, and the amorphous alloy housing 200 is adapted for preventing the functional part 100 from directly contact with the user.

[0026] Specifically, the functional part includes a CPU, a testing part and a communication transmission structure, which are connected and assembled together with other necessary components according to common manners skilled in the art to achieve necessary functions of sport watch including timing, speed measurement, heart rate measurement and data transmission, etc., in this embodiment. In other embodiments, other functional modules also can be set, such as heart rate monitoring module or blood pressure monitoring module, etc.

[0027] The amorphous alloy housing 200 is made of the amorphous alloy mentioned above, especially the side of the housing 200 that is facing to user skin is formed by amorphous alloy material, and thus the housing 200 is antibacterial.

[0028] FIG. 2 is a sectional view of the amorphous alloy housing 200 according to a first embodiment of the present invention. Specifically, the amorphous alloy housing 200 includes a housing 210 and an amorphous alloy layer 220 which is coated on an outer side of the housing 210 by spraying, sputtering, or plating. In such a way, less amorphous alloy material is required to reduce manufacturing cost and obtain good usage experience.

[0029] Furthermore, the amorphous alloy layer 220 is formed on a side of the housing 200 that is facing to the user. In such a way, the appearance of the wearable device will not be affected, and further, less amorphous alloy material is required, instead of covering the whole of the housing with amorphous alloy material.

[0030] Differing from the FIG. 2, FIG. 3 shows sectional view of the amorphous alloy housing 200 according to a second embodiment of the present invention. The amorphous alloy housing 200 is made of amorphous alloy by means of molding process or machining process. Since the amorphous alloy has bactericidal capability, thus the housing 200 made by amorphous alloy also has good bactericidal capability.

[0031] In comparison with prior arts, since the wearable device of the present invention has the amorphous alloy housing 200 covering on the functional part 100, thus the amorphous alloy housing 200 rather than the functional part 100 will contact with the user skin directly. As the amorphous alloy has excellent bactericidal capability, thus user wearing such a wearable device will get a good user experience. Alternatively, the whole of the amorphous alloy housing 200 may be made by amorphous alloy to obtain the excellent user experience; or merely the surface of the housing 210, especially that surface facing to the user skin is made by amorphous alloy to form the amorphous alloy layer 220, thereby reducing manufacturing cost and meanwhile keeping the good bactericidal capability.

[0032] While the invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
