Secure portable, on-demand, microfluidic mixing and dispensing device

A processor-implemented method, comprising:

• receiving, at an at least one processor of a microfluidic mixer device, an instruction to initiate a blend event at the microfluidic mixer device at least in part in response to user input information from a blend software application;
• initiating the blend event at the microfluidic mixer device in response to receiving the instruction, the microfluidic mixer device including:
• a microfluidic mixer device housing;
• a plurality of microfluidic pumps disposed within the microfluidic mixer device housing;
• a plurality of valves disposed within the microfluidic mixer device housing;
• a dispenser at least partially extending through the microfluidic mixer device housing;
• a removable microfluidic mixer chip disposed within the microfluidic mixer device housing and configured with a plurality of fluid channels, the microfluidic mixer chip configured to receive and meter microfluidic amounts of each of at least a first fluid, a second fluid, and an at least one third fluid, each fluid having a viscosity different from a viscosity of each of the other fluids;
• and
• a mix controller disposed within the microfluidic mixer device housing and configured to electronically communicate with the blend software application;
• controlling the microfluidic mixer device to make a microfluidic blend via at least one of the microfluidic pumps and at least one of the valves, and in response to the received instruction, the microfluidic mixer device including a plurality of fluid pathways defined therein and contained within the microfluidic mixer device housing, the fluid pathways including a first fluid pathway providing fluid communication from a first fluid canister containing the first fluid to the microfluidic mixer chip, a second fluid pathway providing fluid communication from a second fluid canister containing the second fluid to the microfluidic mixer chip, a third fluid pathway providing fluid communication from a third fluid canister containing the at least one third fluid to the microfluidic mixer chip, and a fourth fluid pathway providing fluid communication from the microfluidic mixer chip to the dispenser, the dispenser configured to receive metered microfluidic amounts of each of the first fluid, second fluid, and at least one third fluid from the microfluidic mixer chip for dispensing, the controlling the microfluidic mixer device including heating the first fluid pathway based on the viscosity of the first fluid;
• and
• dispensing the microfluidic blend from the dispenser.
