  • ELECTRIC HEATING MAT
    Publication number: 20210207815
    Abstract: The invention relates to an electric surface heater, or heating mat, based on an electrically conductive polymer foil or a conductive polymer foam that only heats locally where persons, animals or objects are positioned on the mat. Energy can thereby be saved in comparison with a full-area heater. Ideally, this local heat generation functions without any external electronic control or regulation.
