Abstract

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the cartridge may comprise a housing defining a liquid reservoir, an atomizer configured to produce an aerosol, the atomizer comprising a first liquid transport element, a second liquid transport element, and a microvalve located between the liquid reservoir and the second liquid transport element. The microvalve may comprise a base member including at least one channel, and an actuating member at least a portion of which comprises a shape-memory material, and which is configured to move between a first position and a second position, wherein in the first position, the actuating member substantially blocks fluid flow from the liquid reservoir through the channel, and in the second position, the actuating member allows fluid flow from the liquid reservoir through the channel and to the second liquid transport element.
