High emissivity far infrared ceramic module for therapeutic device
This invention relates to a ceramic module for assembly into a therapeutic device for treating a human or animal body with irradiation of far infrared. More specifically, said ceramic module can simultaneously emit blackbody-like thermal radiation and stimulated FIR-photons radiation in 3-16 μm wavelength spectrum, while the overall radiation in 8-14 μm wavelength range is measured to be an approximated blackbody radiation at a temperature that is at least 1° K (or 1° C.) higher than the actual body temperature of said ceramic module, signifying an effective emissivity greater than 1.0. Said ceramic module may be used alone or serve as components of a therapeutic device for increasing physiologic performance, immune competence, health, and mean lifespan of human or animal.
1 . A ceramic module for use in a therapeutic device for treating a human or animal body, said ceramic module comprising:
a mixture of three sets of powdered substances, the mixture comprising:
a first set of powdered substance comprising at least one oxide of a first element selected from Group 13 or Group 14 of the Periodic Table of Elements;
a second set of powdered substance comprising at least one oxide of a second element being a transition metal element with a partially-filled 3d or 4d atomic orbital selected from Group 3 through Group 12 of the Periodic Table of Elements; and a third set of powdered substance comprising at least one oxide of a third element being a metal element selected from Group 1 or Group 2 of the Periodic Table of Elements; wherein as a result of said mixture being sintered at a temperature at or above 860° C., said ceramic module has an inhomogeneous crystal structure whereby the ceramic module emits far infrared radiation covering at least a part of 3-16 μm wavelength spectrum, and
wherein the overall radiation over the 8-14 μm wavelength range exhibits enhanced infrared emission due to an additional stimulated emission effect within the ceramic module, resulting in a radiative power output comparable to that of an equivalent blackbody radiator at a temperature at least 1° K or 1° C. higher than the actual body temperature of said ceramic module.
2 . The ceramic module according to claim 1 , wherein said first set of powdered substance includes at least one element selected from boron, aluminum, or silicon.
3 . The ceramic module according to claim 1 , wherein said second set of powdered substance includes at least one element of titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, yttrium, zirconium, or niobium.
4 . The ceramic module according to claim 3 , wherein the at least one element of the second set of powdered substance is zirconium.
5 . The ceramic module according to claim 1 , wherein said third set of powdered substance includes at least one element of lithium, sodium, potassium, magnesium, or calcium.
6 . The ceramic module according to claim 1 , wherein said mixture of powdered substances further comprises a mineral containing at least one oxide of the first element.
7 . The ceramic module according to claim 1 , wherein said mixture of powdered substances further comprises a mineral containing at least one oxide of the second element.
8 . The ceramic module according to claim 7 , wherein the at least one mineral is tourmaline.

10 . The ceramic module according to claim 1 , wherein said ceramic module is configured such that due to the additional stimulated emission effect said overall radiation within the 8-14 μm wavelength range is equivalent to a blackbody radiator at a temperature of at least 2° K or 2° C. higher than the actual body temperature of said ceramic module.
11 . The ceramic module according to claim 1 , wherein said ceramic module is configured such that due to the additional stimulated emission effect said overall radiation within the 8-14 μm wavelength range at a temperature around 36° C. is equivalent to a blackbody radiator whose temperature is at least 38° C.
12 . The ceramic module according to claim 1 , wherein said ceramic module is rectangular, circular, cylindrical, or spherical in shape.
13 . The ceramic module according to claim 1 , wherein said ceramic module is mounted on a flexible substrate for attaching to a body part to be treated.
14 . A method of manufacturing a ceramic module for use in a therapeutic device for treatment of a human or animal body part, comprising:
a) providing a predetermined amount of a first set of powdered substance comprising at least one oxide of a first element selected from Group 13 or Group 14 of the Periodic Table of Elements;
b) providing a predetermined amount of a second set of powdered substance comprising at least one oxide of second element selected from Group 3 through Group 12 of the Periodic Table of Elements;
c) providing a predetermined amount of a third set of powdered substance comprising at least one oxide of a third element selected from Group 1 or Group 2 of the Periodic Table of Elements;
