ABSTRACT:
An electrically heated garment is provided having the effect of protecting the user against the cold. The garment is made of synthetic fiber fabric, polyurethane foam, polyethylene film, a flexible circuit of aluminum foil, and cotton cloth, formed by hot pressing and gluing each layer in sequence. Furthermore, the two ends of the aluminum foil circuit are connected to the output terminals of a heating control circuit device so that heat energy, which is spread all over the clothes, can be adjusted, raising its temperature to keep the user's body warm. The heating control circuit includes an integrated circuit oscillator whose duty cycle is controlled by a potentiometer, without affecting the oscillation frequency.
