A novel solid-state heating element is disclosed. The heating element comprises a plurality of heating layers comprised of a mixture of carbon and a polymer or plastic. The heating layers are disposed on or infused into a substrate. Each heating layer can be disposed on, or infused into, its own substrate, or the heating layers can be disposed on or infused into opposites sides of the same substrate. A radiating element can be disposed in proximity to one or both of the heating layers. The radiating element absorbs the radiation put out by the heating layer(s) and reradiates heat. A heat transfer fluid such as air or a liquid can be directed across the radiating element and/or other areas of the heating element to transfer heat from the heating element to another location.

An electronic vaping device includes a housing, a planar heater, a heater support, a tank, and a wick. The housing extends in a longitudinal direction and has a tip end and a mouth-end. The tip end is closed and the mouth-end has an opening therein. The heater support supports the planar heater. The tank contains a pre-vapor formulation and is configured to slide into and out of the opening of the mouth-end of the housing. The wick extends from the tank and is configured to be in contact with the planar heater when the tank is inserted in the housing.

Provided is an electric grill capable of precisely controlling the temperature of a grilling plate by directly applying a heating paste including carbon nanotubes to the bottom of the grilling plate. The present invention includes the grilling plate on which food to be cooked is placed; a heating body that is applied so as to be arranged on the lower portion of the grilling plate so as to heat the grilling plate; a heat insulating material which is disposed to be spaced apart from the heating body at a predetermined distance so as to block heat conduction to the outside; and a temperature sensor which is disposed between the heating body and the heat insulating material so as to measure the temperature of an upper plate. A pair of electrodes for supplying electricity to the heating body are arranged along opposite edges of both sides of the heating body, and a heating region can be divided and controlled by dividing and combining the pair of electrodes, the heating body, the coating thickness, and the like.
