Abstract: An inhalation device with at least one liquid jet device for producing drops of a liquid on demand, wherein the liquid jet device includes a fluid chamber, an ejection nozzle, a supply channel embedded in a substrate, and at least one heating element arranged to pre-heat the liquid to a predetermined temperature prior to ejection through the ejection nozzle.

Abstract: An inhalation device with at least one liquid jet device for producing drops of a liquid on demand, the liquid jet device has a fluid chamber, an ejection nozzle and a supply channel embedded in a substrate. The inhalation device further includes an air conduit and a mixing chamber in which air from said air conduit is mixed with the generated liquid drops. The air conduit includes at least two heating elements arranged to pre-heat the air guided by the air conduit from a respective air inlet orifice into the mixing chamber.

Abstract: A microfluidic device has a chamber; a fluidic access channel in fluidic connection with the chamber; a plurality of nozzle apertures in fluidic connection with the chamber; and an actuator, operatively coupled to the fluid containment chamber and configured to cause ejection of drops of fluid through the nozzle apertures in an operating condition of the microfluidic device. The chamber has an elongated shape, with a length and a maximum width, wherein an aspect ratio between the length and the maximum width of the chamber is at least 3:1. The nozzle apertures are configured to generate, in use, a plurality of drops having a total drop volume, wherein a ratio total drop volume to a chamber volume is at least 15%.
