Problems solved by technology

Traditional heating tools include electric blankets, baby warmers, etc. Most of them are heated by resistance wires, which pose a safety hazard
Traditional clothing usually improves thermal performance by increasing the number of layers or weight of the clothing. Heavy clothing will bring a certain amount of pressure to the human body, restrict the normal activities of the human body, and even make people feel tired
The existing electric heating materials mainly include metal heating materials, electric heating materials made by coating method, or carbon fiber electric heating materials, etc. Metal resistance wires and coatings have short service life, unstable and uneven heating, poor durability and poor comfort ; while the carbon fiber electric heating fabric has good thermal stability, good design and cutting performance, suitable resistivity, excellent electrical conductivity and thermal radiation performance, especially infrared radiation characteristics
