Electric heating/warming fabric articles

This invention describes a way to make heated fabric by taking a special type of conductive textile, like a fabric coated with metal, and shaping it into an electrical circuit. This circuit is then impregnated with a plastic material and embedded within a fabric laminate to create a durable, warm garment.

Why it matters: Filed in 2005, this predates significant advancements in flexible electronics, miniaturized power sources, and durable conductive textile materials. Modern material science and manufacturing techniques could now enable more robust, washable, and comfortable heated garments than previously feasible.
