DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] A first embodiment of an FIR (Far Infrared) electrically and thermally conductive electrode device in accordance with the present invention is shown in FIGS. 1 and 2 and includes a host 10, an electrode set 20, and a connection assembly 30. As shown in FIG. 2, the electrode set 20 is electrically connected to at least one electrode connecting end 31 of the connection assembly 30, via which the host 10 is electrically connected. In this embodiment, the electrode set 20 includes one or more electrodes. The size and shape of the electrode set 20 can have different designs according to the skin, the body and contact area thereof.

[0028] In this embodiment, the connection assembly 30 and the host 10 are connected in a wireless way using a set of male and female buckle connectors. For example, the connection assembly 30 has a male buckle connector, and the host 10 has a female buckle connector. When the male buckle connection assembly and the female buckle connection assembly are connected, the electrode connecting end 31 is electrically connected to a power loop inside the host 10. As another example, the connection assembly 30 has a female buckle connector, and the host 10 has a male buckle connector. Likewise, when the female buckle connector and the male buckle connector are connected, the electrode connecting end 31 also establishes an electrical connection with the power loop inside the host 10. Furthermore, the set of male and female buckle connectors may be a set of magnetic connectors or a set of magnetic pogo pin connectors. Both have the magnetic and alignment features.

[0029] It is noted that FIR light is generally called the light of life and is the most penetrating light into the skin and deep layers of tissue under the skin. Although human cannot see FIR light with naked eyes, the properties of FIR light are similar to those of visible light, which can not only propagate straight along an optical axis but also get reflected and radiate. Therefore, FIR light can be quickly absorbed by human skins. FIR rays entering human body can cause vibration of the atoms and molecules of the tissues. Through resonant absorption, the temperature of the deep layers of tissue under the skin rises. When used on human skin, the electrode set 20 can achieve the effects of expanding blood capillaries and facilitating blood circulation.

[0030] As shown in FIG. 2, the electrode set 20 includes an electrode protecting layer 21, an FIR heating layer 22, an electrode insulating layer 23, an electrode layer 24, and a conducting gel layer 25. The electrode protecting layer 21 is attached to an upper surface of the FIR heating layer 22. The electrode insulating layer 23 is attached to a lower surface of the FIR heating layer 22. An upper surface of the electrode layer 24 is disposed on a lower surface of the electrode insulating layer 23. An upper surface of the conducting gel layer 25 covers the lower surface of the electrode layer 24.

[0031] Furthermore, the FIR heating layer 22 in this embodiment is prepared by high-temperature carbonization. A polyacrylonitrile carbon fiber (PANCF) is processed at a high temperature (about 1100° C.) as a porous carbon fiber heating material, which can emit FIR rays ranging from 4 to 16 microns (μm) in wavelength at a high temperature. The carbon fiber heating material differs from usual metal heating materials in that it does not generate electromagnetic waves. In this embodiment, the electrode layer 24 may be formed by an electrically conductive printing technique. Alternatively, the electrode layer 24 may contain electrically conductive dopants. Moreover, the electrode layer 24 may be printed on or attached to the electrode insulating layer 23. A lower surface of the conducting gel layer 25 is attached to the skin where requires care for pain relief. In this embodiment, the conducting gel layer 25 achieves electrical conduction via the conductive ions therein. The user can selectively replace the gel layer according to the degree of comfort of electrical stimulations.

[0032] The disclosed FIR electrically and thermally conductive electrode device can be connected to the host 10 via the connection assembly 30. The electrode set 20 is electrically connected to the electrode connecting end 31 of the connection assembly 30, allowing the user to easily replace the electrode set 20. When the host 10 supplies power to the electrode set 20, the set of electrodes 20 can emit FIR rays, generate heat, and make the electrode set 20 electrically conducting, thereby enhancing stimulation effects on nerves in different layers of tissue under the skin. According to the above-mentioned description of the first embodiment, a method for making the electrode of the FIR electrically and thermally conductive electrode device includes steps of: providing the FIR heating layer 22; attaching the electrode protecting layer 21 to the upper surface of the FIR heating layer 22; attaching the electrode insulating layer 23 to the lower surface of the FIR heating layer 22; providing an electrode layer 24 and attaching the electrode layer 24 to the lower surface of the electrode insulating layer 23; and covering the lower surface of the electrode layer 24 with the conducting gel layer 25.

[0033] A second embodiment of an FIR electrically and thermally conductive electrode device in accordance with the present invention is shown in FIGS. 3 to 5. The present embodiment differs from the first embodiment in the structures of the electrode set 20 and the connection assembly 30. This embodiment has an electrode set 20A and a connection assembly 30A. The electrode set 20A includes an electrode protecting layer 21A, an FIR heating unit 26, and a conducting gel layer 25. In this embodiment, the conducting gel layer 25 further includes an insulating layer, a conducting layer 25A, and a gel layer 27.

[0034] With reference to FIGS. 4 and 5, the connection assembly 30A includes a first connector 31A and a plurality of first positioning members 33A. The first connector 31A is installed on the FIR heating unit 26. The plurality of positioning members 33A are provided on an upper surface of the conducting layer 25A. The electrode protecting layer 21A has a plurality of through holes corresponding to the first connectors 31 A and the first positioning members 33A in size respectively. When intending to detachably connect the electrode set 20A to the host 10 via the connection assembly 30A, the user only needs to let the first positioning members 33A on the conducting layer 25A and the first connector 31A on the FIR heating unit 26 go through the respective through holes on the electrode protecting layer 21A for the connection assembly 30A to be fixed to the bottom of the host 10 in a detachable way.

[0035] Furthermore, the host 10 in this embodiment is provided with a second connector 11 and a plurality of second positioning members 12. The second connector 11 on the bottom of the host 10 is connected to the first connector 31A of the FIR heating unit 26, and the second positioning members 12 on the bottom of the host 10 are connected to the respective first positioning members 33A.

[0036] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
