1. A heating apparatus comprising:
a heat source having silicone-based layers comprising:
a first silicone-based layer thermally coupled to a heat transfer body;
a second silicone-based layer disposed on top of the first silicone-based layer;
a heating element layer disposed on top of the second silicone-based layer;
a third silicone-based layer disposed on top of the heating element layer; and
a fourth silicone-based layer disposed on top of the third silicone-based layer, wherein each of the first silicone-based layer, the second silicone-based layer, the heating element layer, the third silicone-based layer, and the fourth silicone-based layer has at least one aperture;
a temperature sensor disposed in the heat source via the at least one aperture of each of the first silicone-based layer, the second silicone-based layer, the heating element layer, the third silicone-based layer, and the fourth silicone-based layer; and
a thermal breaker thermally coupled to the heat source and configured to shut off power to the heat source when the heat source exceeds a predetermined threshold for a predetermined time.
