Liquid cartridge aerosol systems: Philip Morris Int.Recent Research Landscape

Fluid leakage and inconsistent capillary transport represent the primary technical bottlenecks in maintaining reliable aerosol delivery from liquid-based cartridges.

What technical problems is Philip Morris Int. addressing in Liquid cartridge aerosol systems?

Heater thermal distribution inefficiency

(32)evidences

Fluctuating heater temperatures and poor thermal integration lead to scorched liquid or insufficient aerosol density during inhalation.

Cartridge fluid communication failure

(87)evidences

Fluctuations in liquid transport through capillary or wicking elements lead to dry hits or leakage during aerosolization.

Liquid condensate leakage

(80)evidences

Unintended migration of aerosol-forming liquid into the airflow path or device internals causes mechanical failure and poor user experience.
