摘要: A heater is provided for heating an aerosol-forming substrate, the heater including: a heating element to heat the aerosol-forming substrate, the heating element including at least one positive temperature coefficient (PTC) thermistor, the PTC thermistor being configured to be supplied with an electric current so as to heat the PTC thermistor, in which a resistance of the PTC thermistor increases when a temperature of the PTC thermistor increases within a stabilised temperature range, a lower end of the stabilised temperature range being, when a constant voltage is applied to the PTC thermistor, a reference temperature at which the resistance of the PTC thermistor is twice a value of a minimum resistance of the PTC thermistor, and in which the reference temperature is between about 100° C. and about 350° C. when a constant voltage of 3.3V is applied to the PTC thermistor.

摘要: A heating element for an aerosol-generating system is provided, the heating element including: a plurality of first filaments; and a plurality of second filaments, in which the plurality of first filaments are configured to heat a liquid aerosol-forming substrate, the plurality of second filaments are configured to convey the liquid aerosol-forming substrate to wet at least a portion of the heating element with the liquid aerosol-forming substrate, and the heating element is arranged to form a mesh, the plurality of first filaments being arranged in a first direction and the plurality of second filaments being arranged in a second direction, and the second direction being transverse to the first direction. A heater assembly, a cartridge, and a method of manufacturing a heating element, are also provided.
