Terahertz Ring Terahertz ore is said to emit electromagnetic waves called "terahertz waves." Terahertz waves have the characteristics of both radio waves and light, and vibrate one trillion times per second. It is known that this wavelength can penetrate various substances such as wood and plastic, and when applied to the human body, it is known to increase body temperature and improve and activate cell distortion. The history of this research is long, and even in NASA's research conducted from the 1950s to the 1970s, it was concluded that terahertz waves are useful for the human body. In addition, all substances in nature emit weak terahertz waves, and it is thought that they are deeply related to the properties of substances and life activities. Furthermore, research has shown that terahertz ore has a very high thermal conductivity. It is often said that "terahertz ore melts ice," but this is due to the property that heat is easily transferred to ice (high thermal conductivity).
