Abstract
There is provided an electronically controlled, breath actuated vaporization device for generating vaporized material for inhalation by a user. The vaporization device includes a vaporization chamber for accommodating material to be vaporized and a mesh heater or other heater supported upstream of the vaporization chamber which is operable to heat air that passes through the mesh heater or other heater during an inhalation event. A closed loop control scheme may be employed to control heat generated by the heater to maintain a temperature of the air delivered to the vaporization chamber at or within a predetermined tolerance of a desired vaporization temperature for at least a majority of a duration of the inhalation event.
