No, graphene is a new nano-material with light weight, thin thickness, high hardness and strong toughness in the world. It has the characteristics of high strength, high thermal conductivity and strong electrical conductivity. It has the effect of relieving white-collar workers' sedentary backache, cold uterus of women and waist discomfort of the elderly. The products made of it are heated quickly, evenly, thin and close to the body. Cool and relaxing graphene intelligent physiotherapy belt has intelligent heating module, second heating technology, 1 second heating, and 5- 10 second direct contact with skin; Honeycomb heating layout, uniform heating, fast heating and no scalding. If my answer can help you, please adopt it.
