Abstract
A volatile liquid droplet dispenser for containing a liquid to be dispensed, with a first substrate having a space for containing the liquid, and having an outlet with at least one outlet nozzle, the first substrate further having the space adjacent to the liquid outlet, to receive the liquid such that the liquid may exit through at least one outlet nozzle of the outlet, a second substrate having a liquid inlet, and an actuating membrane arranged to actuate liquid in the space.The first substrate also has a fluidic channel interconnected to the space and arranged to laterally connect the liquid inlet to the space, thereby conveying the liquid to the space by way of lateral capillary action. The outlet is eccentric to the liquid inlet and in a vertical plane that is substantially the same or lower than the plane of the liquid inlet, depending on the liquid used.
