An aerosol delivery system includes a perforate membrane including a plurality of apertures, as well as a fluid reservoir in fluid communication with a first side of the perforate membrane and actuation means configured to vibrate the perforate membrane to cause a liquid in the fluid reservoir during use to be ejected as liquid droplets from a second side of the perforate membrane. The plurality of apertures includes first and second arrays of apertures of first and second configurations which are grouped together in first and second discrete regions of the perforate membrane. The fluid reservoir includes first and second reservoir portions and a liquid barrier by which the first and second reservoir portions are separated. A removable cartridge for an aerosol delivery system.

Aerosol delivery system with perforate membrane

A cartridge for an aerosol delivery system. The cartridge includes a fluid reservoir including a first reservoir portion, a second reservoir portion, and at least one liquid barrier configured to separate the first and second reservoir portions. The first and second reservoir portions have respective first and second openings at a first end of the cartridge. The cartridge further includes a perforate membrane located at the first end of the cartridge and over the first and second openings. The first and second openings are configured to supply first and second liquids to a first side of the perforate membrane during use and the perforate membrane includes a plurality of apertures configured to eject one or both of the first and second liquids from a second side of the perforate membrane in the form of liquid droplets when the perforate membrane is vibrated. An aerosol delivery system includes the cartridge.

Cartridge for an aerosol delivery system

A micro-nozzle with an integrated filter structure for receiving fluids at pressures between 0.1 MPa to 50 MPa, comprising: at least one fluid inlet, a fluid outlet comprising at least one orifice, a primary filter structure positioned downstream from the at least one fluid inlet and arranged to provide statistical filtration of fluid passing therethrough.

Micro-nozzle having an integrated filter

A liquid droplet production apparatus comprising a perforate membrane and an actuator. The actuator is configured to vibrate the perforate membrane such that a liquid in contact with the perforate membrane during use is caused to pass through at least one aperture of the perforate membrane and to be ejected as liquid droplets from the perforate membrane. The perforate membrane includes one or more stiffening structures for increasing the stiffness of the perforate membrane, the one or more stiffening structures each being defined by a local transverse deformation of the perforate membrane. A removable cartridge, a perforate membrane, an actuator assembly for use in such a liquid droplet delivery apparatus, and a method of manufacturing a perforate membrane for such a liquid droplet apparatus.
