Abstract
This invention proposes a flexible electrical heating element comprising a substrate, a metal interlayer coating and a far-infrared emissive carbon film. The flexible electrical heating element utilizes a low-cost and environmental friendly vacuum coating technique to deposit the metal interlayer coating and the far-infrared emissive carbon film on the flexible and insulating substrate which can provide uniform heating, and the far-infrared emissive carbon film can emit far-infrared.
