Abstract

Systems and methods of vaporizing liquids are disclosed. In some embodiments, acoustic sources are implemented to motivate fluids out of liquid-containing cartridges in precise quantities such that the fluids can be combined in a desired ratio for later vaporization and inhalation by a user. A liquid cartridge can include a resonance chamber to hold the liquid, where the resonance chamber improves an acoustic source's ability to cause fluid to leave the liquid cartridge when it is vibrated at its resonance frequency. It is also contemplated that systems of the inventive subject matter can include pressure-generating pumps to motivate fluid to leave the liquid cartridges. Liquid leaving cartridges passes into microfluidic channels and later combined before being vaporized for inhalation.
