Abstract
A microfluidic delivery device and method of dispensing a fluid composition from a microfluidic die are provided. The method includes generating air flow from a fan; directing a first portion of the air flow through a first air outlet in a housing; directing a second portion of the air flow through a second air outlet in the housing; jetting a fluid composition from a microfluidic die through a fluid orifice in the housing; directing the second portion of air flow adjacent to the microfluidic die and out the fluid outlet, wherein the first portion of the air flow directs the fluid composition jetted out of the fluid outlet into the air.
