Abstract
A dispensing device, comprising a plurality of microfluidic pumps, microfluidic valves, and a microfluidic mixer chip, for receiving and mixing microfluidic amounts of a plurality of fluids having differing viscosities, is disclosed. The device includes a plurality of pathways for moving fluids from associated reservoirs to the microfluidic mixer chip. A mix controller controls the microfluidic pumps and valves so that the fluids, having different viscosities, can be accurately mixed at specified microfluidic amounts or volumes according to a specified microfluidic recipe, and the microfluidic mixture dispensed from the device. The device can be in communication with a software application implemented on a mobile compute device, such as a smartphone, and receive instructions for implementing the specified microfluidic recipe from the software application such that the operation of device components is at the direction of the software application executed on the mobile compute device.
