Abstract: One or more embodiments are directed to a microfluidic delivery system that dispenses a fluid. The microfluidic delivery system may be provided in a variety of orientations. In one embodiment, the microfluidic delivery system is vertical so that fluid being expelled opposes gravity. In another embodiment, the microfluidic delivery system is orientated sideways so that fluid being expelled has a horizontal component. In yet another embodiment, the microfluidic delivery system faces downward.

Abstract: The present disclosure is directed to a system that is configured to eject fluid vertically away from a thermal microfluidic die for use with scented oils or other fluids. The die is coupled to a rigid planar support board that separates the die from a reservoir of the fluid. The support board includes an opening that is lined with an inert liner that protects an interior surface of the support board from the fluid. The support board includes contact to an external power supply and contacts to the die on a first surface. The die is coupled to this first surface such that the second surface remains free of electrical connections.

Abstract: The present disclosure is directed to a microfluidic die that includes a plurality of heaters above a substrate, a plurality of chambers and nozzles above the heaters, a plurality of first contacts coupled to the heaters, and a plurality of second contacts coupled to the heaters. The plurality of second contacts are coupled to each other and coupled to ground. The die includes a plurality of contact pads, a first signal line coupled to the plurality of second contacts and to a first one of the plurality of contact pads, and a plurality of second signal lines, each second signal line being coupled to one of the plurality of first contacts, groups of the second signal lines being coupled together to drive a group of the plurality of heaters with a single signal, each group of the second signal lines being coupled to a remaining one of the plurality of contact pads.

Abstract: The present disclosure provides supports for microfluidic die that allow for nozzles of the microfluidic die to be on a different plane or face a different direction from electrical contacts on the same support. This includes a rigid support having electrical contacts on a different side of the rigid support with respect to a direction of ejection of the nozzles, and a semi-flexible support or semi-rigid support that allow the electrical contacts to be moved with respect to a direction of ejection of the nozzles. The semi-flexible and semi-rigid supports allow the die to be up to and beyond a 90 degree angle with respect to a plane of the electrical contacts. The different supports allow for a variety of positions of the microfluidic die with respect to a position of the electrical contacts.
