Volatile liquid droplet dispenser device

Volatile liquid droplet dispenser device for connection with a reservoirs containing a liquid substance to be dispensed, the device comprising:

• a first substrate having a space for containing said liquid substance, and having liquid outlet means for ejecting liquid substance from said device, wherein said space is arranged proximate to said liquid outlet means so that liquid substance may exit the space of the device by traversing said liquid outlet means;
• a second substrate containing connection means arranged to receive said reservoir and having a liquid inlet means for allowing said liquid substance to enter said device from said reservoir;
• and,
• an actuating element arranged to actuate liquid substance in said space so that said liquid substance undergoes vibration and contacts the liquid outlet means thereby exiting said device as a liquid droplet spray,
• wherein the liquid outlet means of said first substrate comprises a perforated nozzle membrane having a plurality of outlet nozzles, and
• wherein said first substrates contains at least one fluidic capillary priming channel arranged to receive said liquid substance from said space so as to fill the channel so that said liquid substance is in close proximity to said outlet nozzles for priming said liquid substance for ejection through said nozzle membrane.
