Aerosol delivery devices are provided. The aerosol delivery devices may include a power source configured to output electrical current. The aerosol delivery devices may also include an atomizer in fluid communication with a reservoir containing an aerosol precursor composition, the atomizer being configured to receive electrical current from the power source. The aerosol delivery devices may further include a dispensing mechanism including a shape-memory alloy configured to change shape in response to heat produced from electrical current provided by the power source and to selectively regulate flow of the aerosol precursor composition from the reservoir to the atomizer, the atomizer being configured to produce an aerosol therefrom.

1. An aerosol delivery device comprising: a power source configured to output electrical current;an atomizer in fluid communication with a reservoir containing an aerosol precursor composition, the atomizer being configured to receive electrical current from the power source;a dispensing mechanism comprising a shape-memory alloy configured to change shape in response to heat produced from electrical current provided by the power source and to selectively regulate flow of the aerosol precursor composition from the reservoir to the atomizer, the atomizer being configured to produce an aerosol therefrom; anda flow sensor configured to output a signal corresponding to a draw on the aerosol delivery device and a controller configured to output electrical current to produce heat to change the shape of the dispensing mechanism in response to detection of the draw. 2. The aerosol delivery device of claim 1, wherein the atomizer comprises a liquid transport element and a heating element. 3. The aerosol delivery device of claim 2, wherein the heating element is the dispensing mechanism and includes one or more coils comprising the shape-memory alloy wrapped about the liquid transport element and configured to change from a first shape, where the one or more coils are at least partially spaced apart from an outer surface of the liquid transport element to allow flow of the aerosol precursor composition into the liquid transport element, to a second shape, wherein the one or more coils are in contact with the outer surface of the liquid transport element to heat the aerosol precursor composition at the liquid transport element and thereby produce the aerosol, in response to heat produced from electrical current from the power source. 4. The aerosol delivery device of claim 3, wherein upon cessation of receipt of electrical current at the one or more coils, the one or more coils are configured to return from the second shape to the first shape. 5. The aerosol delivery device of claim 1, wherein the dispensing mechanism comprises a valve. 6. The aerosol delivery device of claim 5, wherein the valve is configured to change from a first shape, where the valve is in a closed configuration to prevent the aerosol precursor composition from being dispensed from the reservoir to the atomizer, to a second shape, where the valve is in an open configuration to allow the aerosol precursor composition to be dispensed to the atomizer from the reservoir, relative to a port defined between the reservoir and the atomizer in response to heat produced from electrical current from the power source. 7. The aerosol delivery device of claim 6, wherein upon cessation of receipt of electrical current at the valve, the valve is configured to return from the second shape to the first shape. 8. The aerosol delivery device of claim 1, wherein the power source, the reservoir, and the atomizer are each housed in separable housings. 9. The aerosol delivery device of claim 1, wherein the shape-memory alloy comprises a nickel titanium (NiTi) alloy. 10. The aerosol delivery device of claim 1, wherein the dispensing mechanism comprises an actuator configured to change from a first shape to a second shape to displace the aerosol precursor composition toward the atomizer. 11. The aerosol delivery device of claim 10, wherein the dispensing mechanism further comprises a piston engaged with an interior of the reservoir, the piston being configured to move along a longitudinal axis centrally defined in the reservoir in response to actuation of the actuator. 12. An aerosol delivery device operation method, comprising: providing a power source, an atomizer, a reservoir containing an aerosol precursor composition, and a dispensing mechanism comprising a shape-memory alloy;heating the dispensing mechanism with electrical current output by the power source to change a shape of the dispensing mechanism in order to selectively regulate flow of the aerosol precursor composition from the reservoir to the atomizer;directing electrical current from the power source to the atomizer to produce an aerosol from the aerosol precursor composition; anddetecting, by a flow sensor, a draw on the aerosol delivery device, wherein heating the dispensing mechanism with electrical current provided by the power source is controlled in response to detection of the draw. 13. The aerosol delivery device operation method of claim 12, wherein providing the atomizer comprises providing a heating element that is the dispensing mechanism and which includes one or more coils comprising the shape-memory alloy and a liquid transport element, the one or more coils being wrapped about the liquid transport element; and wherein changing the shape of the dispensing mechanism comprises changing, of the one or more coils, from a first shape, where the one or more coils are at least partially spaced apart from an outer surface of the liquid transport element to allow flow of the aerosol precursor composition into the liquid transport element, to a second shape, wherein the one or more coils are in contact with the outer surface of the liquid transport element to heat the aerosol precursor composition at the liquid transport element and thereby produce the aerosol, in response to heat produced from electrical current from the power source. 14. The aerosol delivery device operation method of claim 13, further comprising returning the coils from the second shape to the first shape by ceasing the flow of electrical current thereto. 15. The aerosol delivery device operation method of claim 12, wherein changing the shape of the dispensing mechanism, which comprises a valve, comprises changing from a first shape, where the valve is in a closed configuration to prevent the aerosol precursor composition from being dispensed from the reservoir to the atomizer, to a second shape, where the valve is in an open configuration to allow the aerosol precursor composition to be dispensed to the atomizer from the reservoir, relative to a port defined between the reservoir and the atomizer in response to heat produced from electrical current from the power source. 16. The aerosol delivery device operation method of claim 15, further comprising: ceasing receipt of electrical current at the valve; and returning, of the valve, from the second shape to the first shape in response thereto. 17. The aerosol delivery device operation method of claim 12, wherein changing the shape of the dispensing mechanism comprises changing the shape of an actuator from a first shape to a second shape to displace the aerosol precursor composition toward the atomizer. 18. The aerosol delivery device operation method of claim 17, wherein changing the shape of the actuator from the first shape to the second shape comprises moving a piston engaged with an interior of the reservoir along a longitudinal axis centrally defined in the reservoir in response to actuation of the actuator.
