Abstract
An on-demand fluid dispenser to dispense fluid in response to gas generation by a gas cell. The on-demand fluid dispenser includes an expandable gas chamber, a fluid chamber, and an on-demand gas cell. The expandable gas chamber includes a moveable plunger forming a wall of the expandable gas chamber. The moveable plunger also forms a wall of the fluid chamber. The on-demand gas cell is configured to generate the gas on demand. The on-demand gas cell is also configured to direct the gas to the expandable gas chamber to expand the expandable gas chamber. Expansion of the expandable gas chamber moves the moveable plunger to reduce a volume of the fluid chamber and to dispense an amount of fluid from the fluid chamber.
