    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: One or more embodiments are directed to a microfluidic delivery system that dispenses a fluid in a direction that, at least in part, opposes gravity. In one embodiment, the microfluidic delivery system includes a microfluidic refill cartridge that is configured to be placed in a housing. The microfluidic refill cartridge includes at least one nozzle that faces upward or off to a side. The microfluidic refill cartridge includes a fluid transport member that allows fluid to travel upward from a fluid reservoir in opposition to gravity. A fluid path is located above the fluid transport member placing an end of the fluid transport member in fluid communication with a chamber and a nozzle. In response to the microfluidic delivery system receiving an electrical signal, an ejection element is configured to cause fluid in the chamber to be expelled through the nozzle. In response to the fluid being expelled from the nozzle, fluid may be pulled up through the fluid transport member and through the fluid path to refill the chamber.
