More Information
Summary:A nicotine e-vaping device may include a device body configured to receive a nicotine cartridge. The nicotine cartridge includes a nicotine pre-vapor formulation, a wick, and an integral heater-thermocouple. The wick is configured to transport the nicotine pre-vapor formulation by capillary action. The integral heater-thermocouple includes a first segment made of a first alloy and a second segment made of a second alloy. The device body includes a power supply, at least one sensor, and a controller. The power supply is configured to deliver electrical energy to the integral heater-thermocouple to heat the nicotine pre-vapor formulation to generate a nicotine vapor. The at least one sensor is configured to measure a voltage difference between the first segment and the second segment of the integral heater-thermocouple during such heating. The controller is configured to adjust the electrical energy to the integral heater-thermocouple based on the measured voltage difference.
