Abstract: Ejection device for fluid, comprising a solid body including: first semiconductor body including a chamber for containing the fluid, an ejection nozzle in fluid connection with the chamber, and an actuator operatively connected to the chamber to generate, in use, one or more pressure waves in the fluid such as to cause ejection of the fluid from the ejection nozzle; and a second semiconductor body including a channel for feeding the fluid to the chamber, coupled to the first semiconductor body, in such a way that the channel is in fluid connection with the chamber. The second semiconductor body integrates a damping cavity over which extends a damping membrane, the damping cavity and the damping membrane extending laterally to the channel for feeding the fluid.

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 microfluidic die that includes ejection circuitry and one time programmable memory with a minimal number of contact pads to external devices. The die includes a relatively large number of nozzles and a relatively small number of contact pads. The die includes decoding circuitry that utilizes the small number of contact pads to control the drive and ejection of the nozzles and the reading/writing of the memory with the same contact pads.

Abstract: A microfluidic MEMS device is formed by a plurality of ejection cells each having a fluid chamber; an actuator chamber; a membrane having a first surface facing the actuator chamber and a second surface facing the fluid chamber; a piezoelectric actuator on the first surface of the membrane; and a passivation layer on the piezoelectric actuator. The membrane has an elongated area defining a longitudinal direction and a transverse direction. The passivation layer has a plurality of holes. The holes extend throughout the thickness of the passivation layer and, in a plan view, have an elongated shape with a greater dimension parallel to the longitudinal direction of the membrane and a smaller dimension parallel to the transverse direction.

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.
