1. A cartridge for a vaporization device, the cartridge comprising:
- a flattened body having a long axis and a short axis;
a reservoir configured to hold a vaporizable material within the flattened body;
a heater chamber at an end of the cartridge;
a resistive heater comprising a pair of plates on a first side and a second side of the heater chamber extending in the long axis and a wick suspended between the plates extending in the long axis, and a resistive heating element directly in contact with the pair of plates and with the wick, wherein the wick is configured to contact the vaporizable material from the reservoir; and
a pair of exposed flat contact tabs integrally formed from the plates and extending from the resistive heater and folded over an outer surface of the end of the cartridge and configured to complete a circuit with the vaporization device when the cartridge is inserted into the vaporization device.

Abstract
Vaporization devices and methods of operating them. In particular, described herein are methods for controlling the power applied to a resistive heater of a vaporization device by measuring the resistance of the resistive heater at discrete intervals. Changes in the resistance during heating may be used to control the power applied to heat the resistive heater during operation. Also described herein are vaporization devices that are configured to measure the resistance of the resistive heater during heating and to control the application of power to the resistive heater based on the resistance values.

14. A cartridge for a vaporization device, the cartridge comprising:
-
a flattened body having a long axis and a short axis; a reservoir holding a liquid vaporizable material within the flattened body; a heater chamber at a distal end of the flattened body; a resistive heater comprising a pair of plates on a first side and a second side of the heater chamber extending in the long axis and a wick suspended between the plates, and a resistive heating element directly in contact with the pair of plates and in thermal contact with the wick, wherein the wick contacts the vaporizable material in the reservoir; a pair of exposed flat contact tabs integrally formed from the plates and extending from the resistive heater and folded over an outer surface of the distal end of the flattened body and configured to complete a circuit with the vaporization device when the cartridge is inserted into the vaporization device; and a raised rail on each side of the flattened body.
