Abstract
A microfluidic delivery device and method of dispensing a fluid composition therefrom is provided. The microfluidic delivery device includes a housing electrically connectable with a power source; a cartridge releasably connectable with the housing; and a fan connected with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The die is configured such that substantially all of the fluid composition exits the microfluidic die in a horizontal direction or downward direction relative to horizontal. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in an upward direction relative to horizontal.
