The automatic heat controlled ceramic semiconductor is composed of far infrared ray materials, heat materials, and control components. It starts with a ceramic energy non-conductor. Material is added which will conduct electricity, making a semi-conductor that radiates between 4 um and 14 um, the narrow part of the far infrared band suitable for theraputic purposes.

Automatic temperature control components are added. These devices enable the ceramic semi-conductor to decrease the electric current when the temperature is too high, and to increase the electric current when the temperature is too low. Thus heat is kept within a range between 140F and 170F while the semi-conductor continuously radiates 95-99% pure far infrared energy.
