An electronic cigarette with an improved atomizer includes a suction nozzle and a main body. The main body is provided with an atomizing core mounting groove. The atomizing core mounting groove contains an atomizing core. The suction nozzle and the main body are integrated into one piece, or the suction nozzle and the main body can be connected to or detached from each other. The atomizing core includes a casing, a liquid storage assembly, and a heating assembly. A wire passes through a first wire guide hole and is electrically connected to a power supply and a control system. A first air guide hole and a second air guide hole are connected through which an airflow passes.

A method for manufacturing a heating device having a carrier and at least one heating conductor applied thereto has the steps: provision of a carrier having a heating conductor side, wherein the carrier consists of aluminum, generation of an anodized layer on the heating conductor side, wherein the anodized layer is applied directly to the carrier and/or its heating conductor side, application of the at least one heating conductor above the anodized layer in a thick-film method. Advantageously, the anodized layer can be manufactured as a hard anodized layer. An additional insulation layer and/or a thickening layer can also be applied to the anodized layer.

Disclosed herein is a thermal radiation modulation system comprising a first low emissivity layer comprising a plurality of distributed, strain-dependent cracks, the first low emissivity layer comprising a first polymer composite layer and a first mirror-like metal layer with low emissivity covering a surface of the first polymer composite layer; a first elastomer layer bonded to the first low emissivity layer opposite to the mirror-like metal layer; and optionally a first stretchable heater, the first stretchable heater is attached to the first elastomer layer opposite to the first low emissivity layer, wherein a top surface of the first low emissivity layer comprising the mirror-like metal layer has a lower emissivity relative to the first elastomer layer. Methods of making and use of the system are further described.

An article comprising a heater that comprises a high-resistance magnification (HRM) PTC ink deposited on a flexible substrate to form one or more resistors. The HRM PTC ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature T and a resistance of the double-resin ink at 25 degrees Celsius.
