1. A heating device comprising:

  • at least one conducting device having;

    a conducting-part carrier core comprising a synthetic material, the synthetic material of the conducting-part carrier core at least partially decomposes at a temperature between about 200°

    C. and about 400°

    C.;

    a conductive part partially or entirely disposed on the conducting-part carrier core and in electrical communication with a current source;

    a connector cable connecting the at least one conducting device to the current source;

    wherein the conducting-part carrier core comprises a material that exhibits a high resistance to back-and-forth bending and has a tensile strength of more than 2500 N/mm2;

    wherein the conductive part exhibits zones of different material gauge including one or more cuts, swellings, and/or recesses;

    wherein the synthetic material of the conducting-part carrier core is comprised of a material in at least 50% crystalline form and a remainder of the material is an amorphous structure;

    wherein the synthetic material has a crystallinity of at least 50 J/g;

    wherein the synthetic material of the conducting-part carrier core has a molecular weight of 130,000 g/mol or more; and

    wherein an electrical conductivity of the at least one conducting device is permanently shut off when the synthetic material of the conducting-part carrier core at least partially decomposes.
