摘要：
An apparatus includes a housing including a power source； a reservoir including an inlet, an outlet, and configured to contain vaporizable material and couple to the housing； and a PTCR heating element configured to electrically couple to the power source and heat the vaporizable material to form an aerosol. The PTCR heating element includes an electrical resistivity that varies based on temperature. The electrical resistivity includes an electrical resistivity transition zone including an increase in electrical resistivity over a temperature range such that, when the PTCR heating element is heated to a first temperature within the transition zone, current flow from the power source is reduced to a level that limits further temperature increases of the PTCR heating element. Related apparatus, systems, techniques, and articles are also described.
