ABSTRACT:
The invention provides a flexible electro-heating apparatus and fabrication thereof. The electro-heating apparatus, according to the invention, includes a fabric-type heating device, at least one pair of terminals, and a power supply. The heating device is formed by at least M first yarns which each first yarn substantially consists of first textile fibers and metal fibers or metallic fibers. N first yarns of the M first yarns are woven through the heating device from a first side of the heating device to a second side of the beating device. Each pair of terminals is respectively and oppositely disposed on the first side and the second side of the heating device. When the power supply electrically connects to the terminals disposed on the first side and the second side of the heating device, the power supply is, capable of applying a voltage between the first side and the second side of the heating device such that an electric current resulting from the voltage flows through the N first yarns woven through the beating device from the first side to the second side. The N first yarns then generate heat induced by the electric current.
