Abstract
A vaporizer device including a vaporizer cartridge configured to efficiently and effectively heat a non-liquid vaporizable material is described. The vaporizer cartridge may include a heating element configured to vaporize the vaporizable material by delivery of heat to the vaporizable material. The cartridge may include a cartridge contact in electrical communication with the heating element. The cartridge contact may be configured to couple to a receptacle contact along a vaporizer body of the vaporizer device having a power source to allow power to pass from the power source to the heating element. The heating element can include electrically resistive features such that current traveling along the heating element can cause the heating element to increase in temperature to within a desired temperature range. Related systems, methods, and articles of manufacture are also described.
