Memory cotton, also known as slow rebound, was developed in the 1960s by the United States National Aeronautics and Humanities Corporation (USAHMAN), a subsidiary of NASA, and is an open cell structure. Characteristics. It can also be referred to as a temperature-sensitive decompression material. The company HEALTHMAN applied this material to the space shuttle. In order to relieve the pressure on the astronauts and protect the astronauts' spine, the astronauts are particularly exposed to the most stress and danger when the space shuttle returns and leaves the ground. In order to protect the astronaut's safety, this material was invented. He and GPS (Global Positioning System) are also known as two major inventions of space science and technology. The largest science in the 21st century will be life sciences, and space science and technology will make a great contribution to the research of human life sciences. In the early 1990s, the Swedish company Fagerdala was once again developed as a civilian (medical) product, and was first widely used in medical emergency and monitoring systems. Then it quickly spread in developed countries, especially in health-conscious countries such as Japan.
The slow slow rebound material of the company's HEALTHMAN company is the second generation of Visco-Elastic material developed by NASA's Health and Wellness Sleep Research Center. The so-called warm feeling refers to the induction of human body temperature. Decompression is to absorb body pressure. When the human body touches the material, the material will sense the human body temperature, gradually become soft, and at the same time absorb the human body pressure, thereby adjusting the human body to the most comfortable posture state. What is shown on mattresses and pillows is that when a person is lying on a mattress and a pillow, the spine is in the natural physiological bending state of the S-type when lying on his back, and the spine does not bend sideways when lying on his side. At the same time, mattresses and pillows do not have a stress point on the human body. This is the material.
